Innovative Service Improves GPS Accuracy

Mon, 14 Jul 2008 00:00:00 -0500

The Global Positioning System (GPS), a worldwide radio-navigation system, is the tool of choice to collect spatial data for Geographic Information Systems (GIS). GIS data collected with GPS can support a variety of activities, including mapping and spatial analysis.

A stand-alone GPS receiver provides accuracies of approximately 5-15 meters in relation to the global reference frame; however, GPS positioning is subject to several error sources, such as atmospheric effects, satellite orbits and satellite clocks. These factors cause errors in the range-to-satellite, which amount to errors in position. Differential GPS (DGPS) corrections can be used to reduce these errors.

The MTO, in partnership with the Ministry of Natural Resources (MNR), other provinces, territories and the federal government, have developed a new differential correction service to produce DGPS corrections, thereby increasing GPS standalone accuracy to about 1-2 meters (for high quality GPS receivers). The Canadian Differential Global Positioning System, or CDGPS, is the result of four years of development. The CDGPS radio receives a DGPS correction model via the MSAT-2 geostationary satellite, calculates corrections localized to the user, and outputs these corrections to a GPS receiver in standard format.

This free service is available for the entire Canadian landmass, including the far north. Other free DGPS services, such as the marine beacon and Wide Area Augmentation System (WAAS), fall short in this respect. Other commercial services involve yearly subscription plans in order to receive corrections.

The radio has a one-time cost of about $1,500. This does not include the cost of GPS equipment. After purchase, the service is free of charge.

CDGPS is the only service that provides corrections yielding positions directly relating to the Canadian Spatial Reference System - North American Datum 1983 (NAD83). WAAS, for example, outputs positions on the World Geodetic System 1984, which is different from NAD83 by as much as a meter. CDGPS was declared operational in October 2003. Shortly after, the Geometrics Office conducted several tests to determine the increase in accuracy possible using CDGPS corrections with various grades of GPS receivers under different conditions.

The tests confirmed the expected accuracy of about 1.5 meters for high quality GPS receivers using CDGPS.

What this means for the MTO is that anyone can purchase a standard piece of equipment to augment a high quality GPS receiver, in order to achieve meter-level positioning for their GIS data or mapping products. The development of CDGPS technology represents a progressive movement to enhance existing GPS positioning

An Introduction to Culvert Pipes

Mon, 11 Jun 2007 00:00:00 -0500

A culvert pipe is a cutting under or beside a road that allows water to drain, rather than pooling and creating hazardous conditions. Technically, only an enclosed channel under a road could be further classified as a culvert, and a cutting next to a road is recognized as a ditch. Culverts Pipes are a very important part of the system used to drain roads and drives, keeping them secure and extending their lifetimes.

Ideally, a culvert installation is done when a road is built, either by the home highway authority or a property owner, only in case if the culvert is on private land. Generally, if a section of a road lies in a dejected area of ground or an area subject to flooding, a culvert need to be installed to facilitate drainage problems, especially in the winter. The culvert pipes are laid into the road bed as it is being built, and is kept apparent by maintenance crews during everyday checks of the roadway throughout the year.

Generally culverts serve two chief functions. The first is that a culvert permits water to drain under the road, rather than pooling it on top, making the surface secure for drivers. Pooled water on a road could cause cars to hydroplane, cover up hazards on the roadway, and would eventually eat away at the roadway, causing it to smash down quickly. If a road floods in excess of, it might have to be closed until the water level recedes that is trying for drivers, but necessary for safety.

The second function of a culvert is to hold up water from gathering along the margins of the highway and grasping away at the base of the road bed. This expands the life of the road and put off the edges of the roadway from gradually crumbling away, posing a security hazard to drivers. In addition, if the water level next to the road rises in excess of, it could start to flood onto the roadway, forcing road closure until the water level falls again.

A culvert construction could be done from a huge variety of materials, depending on the size and where it is installed. Concrete, metal, and plastics are all general choices to line the cutting used to make a culvert pipes safety ends, preventing the sides from caving in. If a culvert is not helpful enough, it might be replaced with a small raised bridge to raise the roadway above the frequently flooded area.

Get away from poor drainage problem

Mon, 11 Jun 2007 00:00:00 -0500

Poor drainage is the ultimate and leading cause of death for our beautiful garden plants. Adding up organic matter would enhance poor drainage problem. If you have tried that, though, and your land clearing site still remains watery for hours after a short, heavy rain, then further action is now required. Shallow trenching and drainage pipe could solve the problem. Please follow the below given instruction for further drainage solution.

Instructions

* Look for a spot below the level of your garden where the water could drain away safely. A storm drain, dry well or even drainage ditch is an perfect choice.

* Calculate the distance from the lowest point in the trouble site to your drainage area. Then purchase enough perforated 4-inch (10-cm)- diameter drainage pipe to cover that particular distance.

* Dig a trench 18 inches (45 cm) deep and 12 inches (30 cm) wide, sloping below among the two points. Try for a drop of about 1 inch (2.5 cm) for each 10 feet (3 m) of ground.

* Test the slope by driving a glide into the soil at every end of the trench. Run a string among the two glides, and use a spirit level to calculate the drop among them.

* When the slope is at the correct angle, line the trench with about 3 inches (7.5 cm) of gravel or crushed stone.

* Lay the pipe on the stone (see B), and ensure that any joints are completely fastened tightly.

* Cover the pipe with agricultural fabric to defend soil from clogging the perforations (tuck the cloth under the pipe towards the uphill opening).

* Add another 6 more inches (15 cm) of stone over the drainage pipe.

* Finally replace the soil in the trench.

Tips & Warnings

* If your drainage problem is very serious, you might really need expert to help. Before you try any do-it-yourself steps, ask a land clearing contractor.
* On a large residential or commerical site, consider just going with the flow. Many beautiful plants, including cardinal flower, Japanese iris and astilbe, thrive in moist soil.
* Another option to expensive, time consuming drainage correction is to grow your plants in any well defined containers.

All about Concrete mixer

Thu, 17 May 2007 00:00:00 -0500

A concrete mixer, as the name states is a tool, which mixes cement with water and other additives like sand and gravel. Ranging from big profitable concrete mixer trucks to moveable mini mixers, this power-driven device usually comprises of a motor, a revolving drum and a chute. The materials used in creating concrete spin around in the drum, mixing consistently and are set for application or pouring.

Commercial concrete mixer

For large-scale projects plan, a huge commercial concrete mixer truck is usually used for mixing concrete and other transporting it to the excavation site. Concrete companies, which provide such services generally, ask for right to use to the building site as near as likely. Also, as concrete could dry fast, it is significant to have concrete finishers to pour and be relevant the concrete as fast as possible. Most truck providers charge per cubic yard of concrete amount ordered for.

Mini concrete mixer

A mini concrete mixer is a moveable concrete mixer, which carry the work of a commercial concrete mixer, but on a low level scale and is normally used where lesser volumes of concrete are in fact required. Homeowners who would desire to carry out minor fix activities or try their skills at installing gardens, driveways or concrete slabs, which have broken down. A moveable mini concrete mixer does the job on electricity and has a stand with wheels for easy transport. The small revolving drum in the concrete pad mixer could be tilted down that actually makes it simple to fill a wheelbarrow with set concrete for use.

Tips for using concrete mixers

It is significant to remember that even though a concrete mixer arranges concrete for application and keeps it soft and set to use, it would not be able to keep the concrete in available condition for a long time. The time necessary for setting for various kinds of concrete is dissimilar and the handyman might be required to decide precisely how much concrete is necessary for a specific task or for a land clearing process. For big land clearing projects, concrete contractors are usually aware of the amount of concrete, which have to be used on an each day. Hence, chances of waste and drying of concrete is least in such cases.

The Basics of "Short Sales"

Tue, 15 May 2007 00:00:00 -0500

You may likely come across dozens of properties in foreclosure with little or no equity, that is, the seller owes at close to or more than what the property is worth. In these situations, lenders are sometimes eager to accept less than the full amount due, usually referred to a "short pay" or "short sale".

Negotiating a short sale with the lender is a hard process, usually because it is an off-putting task finding a bank officer who has the authority to allow a discount. You will have to call around to situate the lender's Loss Mitigation Department. More than likely, each lender you deal with would have a different name for this department, so be patient when calling. Much like getting your phone bill corrected, you could anticipate the process to involve a lot of waiting on hold and being bounced around a complex maze of automated voice mail systems. Once you get in touch with the right person, then the bargain begins.

From the lender's viewpoint, a short sale saves many of the costs related with the foreclosure process - attorney fee's, the eviction process, delays from borrower insolvency, damage to the property, costs related with resale, etc. In a short sale scenario, the lender gets the property back faster, so it is able to cut its losses. Your job as the investor is to persuade the lender that it would fare better by accepting less money now.

The lender would desire some information about the property, the borrower and the deal he has made with you. Particularly, the lender needs to know what the property is worth. The lender would usually hire a local real estate broker or appraiser to evaluate the property (known a broker's price opinion or BPO). You could also submit your own assessment or comparable sales information. In addition you would desire to offer as much precise negative information about the property as possible. Also, contain some relevant information about the neighborhood and the local financial system if things are bad (copies of newspaper articles with bad news can help). A contract's bid for repair estimates must also be submitted, which, of course, must be the highest bid you could obtain!

Don't be surprised if your short sale offer is rejected. Lenders are not emotionally attached to their properties, so they aren't as likely to give you steal. Many short sales fall through if the BPO comes in too high, this is frequently the case. You can't pull the wool over a lender's eyes - if the property isn't is require of serious repair, it is improbable you could convince the lender the property is value a whole lot less than the appraised value.

Determine the profit on your Real Estate sale

Fri, 11 May 2007 00:00:00 -0500

Most people look to compromise in their area to come up with the listing price for their property. This is logical, but you also have to hub on the bottom line.

How Much Would You Make on The Sale of Your Property?

It happens more frequently than you might imagine. A homeowner decides to sell and goes about figuring the top price to sell. They might set a price off of the cuff or does study to ascertain the best price that will result in a sale within a specific time period. What many do not take into account, nevertheless, is the ultimate amount would get from the property. This could lead to brutal surprises when the eventual amount is much less than expected a concept known as seller’s remorse.

In realism, the decision to sell your property must only be made after determining what you could objectively get out of it. Most people, however, lean to eyeball this amount. If you have a lot of justice in the property, it in fact is not an issue. If you don’t, you better start calculating or you can be in for a bad shock.

The first place to start is the predictable price you would sell for minus the outstanding balance on your mortgage. This gives you a rough estimate of your equity, but must not be relied upon as the final cash out figure. Instead, you have to sit down and start calculating the other costs such as:

* Mortgage pre-payment penalties,
* Property taxes for the part of the related year in which you are selling.
* Any costs connected with repairs to the property to get it in shape to sell.
* Attorney’s fees if a lawyer is necessary to be part of the process in your state.
Incidental costs connected with the sale as agreed to in the purchase agreement with the buyer. Items could include title insurance premiums, recording fees, examination fees, warranty insurance, escrow fees and so on.
One area people totally forget to factor in is, ironically, the main expense. If you use a real estate agent, you are going to pay an important commission. A typical 6 percent commission on the sale of a $300,000 home is $18,000. More and more sellers are bypassing this by selling their properties without agents, which makes brains given the money involved. Regardless, you require ascertaining how you would sell the home and the relevant cost of doing so as part of your overall calculation. Making the choice to sell is an emotional one. It should, however, also comprise a hard, cold look at the financials involved and whether doing so makes sense.

Stretcher-bond path

A stretcher bond paving pattern is one of the simplest paving designs. Depending on the land clearing area and the position of the viewer, the paving pattern could make an area look larger or smaller. In this instance, the pavers are laid lengthways that makes the path look longer that it actually is. A header course at the edge of the path assists defines the space.

Stretcher/header combo path
