Ezigrade is designed for farmers and land/survey contractors to easily design Land Grading and Land Forming solutions. Touchwiz icon pack zip. Land Grading is where you fit a plane of best fit to the surface. This is typically used for irrigation solutions. Ezigrade allows you to design multiple fields. Research has shown yield improvements of up to 15%; and Ezigrade helps you achieve the suitable grades with a minimum of effort. Land Forming is where you grade and optionally smooth the surface to achieve a drainage solution. You typically constrain grades both along main and cross slopes, to remove ponding and achieve erosion control.
Typically the amount of dirt to be removed is reduced. Reducing the cost. This is particularly advantageous in dryland situations. Ezigrade is versatile and you can design many different scenarios:. A single plane solution.
A multiplane solution. Multiplane solution with smoothed joins. Multiplane solution with hinged joins. Variable grades to allow water drainage - with corresponding reductions in earth movement. Furrow design around a pivot point. Ie Grade around a circle - both Plane and Variable grades. Design a surface drain as part of the solution.

Design structures for surface water control. For example a ring tank or dam. Ezigrade is compatible with a number of different agricultural systems and civil engineering software. Some typically supported systems are:. Level Guide and Farmscan. Trimble™ Field Level 11. Topcon™ Civil.
Other systems via landxml and dxf/dwg. Lidar data via drone - for example 3DC Sensefly Ebee RTK Drone. Ezigrade can also interface directly with your RTK GPS and pickup data directly from NMEA data.
If you are designing for Trimble Field Level system we have a free viewer that allows you or the earth moving contractor to display the design before loading on the tractor. Users of other design software can use this as well for no charge. Please go to Please click on the following link to view some typical design's. Please click on the following link to view a case study of a multiplane type design. I suggest you view some of our video's that show you how to create some typical designs.

Center for Operational Oceanographic Products and Services staff member conducts tide station levelling in support of the US Army Corp of Engineers in Richmond, Maine. Levelling or leveling (; ) is a branch of, the object of which is to. Find the elevation of a given point with respect to the given or assumed. Establish a point at a given elevation with respect to the given or assumed.
Levelling is the measurement of using an optical levelling instrument and a or rod having a numbered scale. Common levelling instruments include the, the, the digital level, and the. Further information: Older instruments The wye level is the oldest and bulkiest of the older style optical instruments. A low-powered telescope is placed in a pair of clamp mounts, and the instrument then leveled using a, which is mounted parallel to the main telescope.
The was developed by English civil engineer, while surveying the route of a proposed railway line from London to Dover. More compact and hence both more robust and easier to transport, it is commonly believed that dumpy levelling is less accurate than other types of levelling, but such is not the case. Dumpy levelling requires shorter and therefore more numerous sights, but this fault is compensated by the practice of making foresights and backsights equal. Precise level designs were often used for large leveling projects where utmost accuracy was required. They differ from other levels in having a very precise spirit level tube and a micrometer adjustment to raise or lower the line of sight so that the crosshair can be made to coincide with a line on the rod scale and no interpolation is required.
Automatic level. This article contains. The purpose of Wikipedia is to present facts, not to train. Please help either by rewriting the how-to content or by it to,. (May 2015) Automatic levels make use of a compensator that ensures that the line of sight remains horizontal once the operator has roughly leveled the instrument (to within maybe 0.05 degree). The surveyor sets the instrument up quickly and doesn't have to relevel it carefully each time he sights on a rod on another point. It also reduces the effect of minor settling of the tripod to the actual amount of motion instead of leveraging the tilt over the sight distance.
Three level screws are used to level the instrument. Gun sight. Circular level (pond bubble). Levelling Screw. Base Plate. Objective Lens. Focusing Knob.
Horizontal fine motion screw. Horizontal circle window. Horizontal circle setting ring.
Reticle adjusting screw cover. Eyepiece Setting up an automatic level Set up the tripod at just above chest height.

Make sure it is stable, and mount the level on the top. Adjust the leveling screws until the pond bubble is centralised. As long as the pond bubble is central, the automatic compensators are able to finely level the instrument. To ensure this is the case, whilst looking through the scope, gently tap the level.
The view will waver for a few moments before steadying. If this does not happen, the instrument is not level enough for the compensators to cope, and needs adjustment. Sighting Sight towards the staff using the gun sight. Look through the eyepiece and focus the reticle by gradually turning the reticle focusing ring anti-clockwise. Turn the focusing knob to focus on the staff. Turn the fine motion screw to centre the staff in the field of view.
Turn the focusing knob to eliminate parallax between the staff and reticle. The Reading the staff The staff starts at zero, on the ground.

Every 10 cm is a number, showing ( in meters to one decimal) the height of the bottom of what appears to be a stylised E (even numbers) or 3 (odd numbers), 5 cm high. The stems of the E or 3 and the gaps between them are each 10mm high. These 10mm increments continue up to the next 10 cm mark. To read the staff, take the number shown below the reticle. Count the number of whole 10mm increments between the whole number and the reticle. Then estimate the number of mm between the last whole 10mm block and the centre of the reticle.
The person holding the staff should endeavour to hold it as straight as possible. The leveller can easily see if it is tilted to the left or right, and should correct the staff-holder.

However, it cannot easily be seen that the staff is tilted towards or away from the leveller. In order to combat this possible source of error, the staff should be slowly rocked towards and away from the leveller. When viewing the staff, the reading will thus vary between a high and low point. The correct reading is the lowest value. Digital levels electronically read a bar-coded scale on the staff. These instruments usually include data recording capability.
The automation removes the requirement for the operator to read a scale and write down the value, and so reduces blunders. It may also compute and apply refraction and curvature corrections. Laser level. Main article: Laser levels project a beam which is visible and/or detectable by a sensor on the leveling rod.
Leveling Instruments In Surveying
This style is widely used in construction work but not for more precise control work. An advantage is that one person can perform the levelling independently, whereas other types require one person at the instrument and one holding the rod. The sensor can be mounted on earth-moving machinery to allow automated grading. See also. References Wikimedia Commons has media related to.
