The results from each of the volume measurements are listed in the Mensuration Results pane and compiled in the measurement report. This is because the volume measurement is calculated using the elevation surface dataset defined in the Mensuration Options pane. The only requirement is that features and objects digitized in the layer should be represented in the elevation dataset to obtain accurate volume measurements. Note:The raster layer used as a backdrop for digitizing your features of interest can be a multispectral image, thematic, an elevation surface, or another type of supported raster dataset. The total volume measurement is cut value + fill value. Ground features below the base surface result in fill values, and above ground features result in cut values. When the pile is calculated, the outputs are in Cut and Fill volumes. Once you double click to finish the annotation, Terra will calculate the volume of the pile. Mean-Uses the mean z-value from the sketch vertices to define a flat base surface at the mean elevation.Ĭut and fill volumes are calculated from the difference between the digitized feature and the defined base surface. To measure a stockpile, select the Volume tool and click around the stockpile.Maximum-Uses the maximum z-value found in the sketch vertices to define a flat base surface at the maximum elevation. Minimum-Uses the minimum z-value found in the sketch vertices to define a flat base surface at the minimum elevation.Interpolate-Uses the z-value at each vertex in your sketch to interpolate a base surface for the volume calculation.Amount of soil to stockpile, Amount compost needed, Amount topsoil needed. Constant-A user defined value that defines a flat base surface The Compost and Topsoil Calculator below is for use by permit applicants to.The reference surface-called the base surface-can be created using any of the following Base Surface options: The volume measurement is calculated from a reference surface determined by the polygon delineating the object you want to measure. If you have a choice of elevation surface types for your area of interest, it is recommended that you use a DSM, which best represents the elevation of features above the ground. You can measure the volume of objects in a DSM, DTM, DEM, or other elevation dataset using the Volume tool in the Mensuration gallery. Soil and rock expansion - or swell - after mining. With geo-referenced images captured by a drone flying above your worksite, you can use photogrammetry to generate a 3D map of your site with measurements accurate to 1/10ft (3cm). The calculator below can be used to calculate volume and mass of a coned pile. Draw a polygon around the feature to calculate and display cut and fill volumes in the map, the Results pane, and the measurement report. You can also compare stockpile surveys to a final grade design file to calculate how much material you still need to add or remove. Pricing for the service is unfortunate unpublished, but you can fill out this form to inquire about pricing for your job site.Volume of features can be measured from any georeferenced raster dataset, mosaic dataset, or image serviceĬomprised of an elevation surface such as a digital surface model (DSM), digital terrain model (DTM), or digital elevation model (DEM). The excavated soils within Section 1 of the garage continued to be dumped on Stockpile 1 to form a 10-m-high stockpile (Phase 2) behind Buildings 67, and the excavated soils within Section 2 were dumped on the landscaping area between Buildings 1011 and the Dingpu River to form a 6-m-high stockpile (Stockpile 2) refer to Fig. More importantly you gain valuable historical data with a few clicks of a button. The calculator searches the circular slip surface for which the factor of safety is minimal. It is a slightly modified JavaScript clone of the slope stability software STABR Ver. It uses the Bishop Modified and/or Ordinary Method of Slices for a 2-dimensional setting. Droneįor those contractors that are partaking in the drone craze, you can even use your own drone to take aerial images of your stockpiles, upload them to the program, and get your results.Īccording to the company website, the accuracy of the data is between 2-4%. This calculator determines the factor of safety for a soil slope. The only other thing the users need to do is tag the stockpile and view the results. Aerial PhotosĬustomers of Stockpile Reports can request an aerial flight directly through the company and will receive their stockpile data within hours of the flight. The iPhone app can be downloaded by clicking here. Simply position the cones 25 feet (10m) apart and in front of the stockpile, select the stockpile material in the Stockpiles app, and walk around the pile while taking a video. The great thing about this app is that it doesn’t require any special equipment or training, just an iPhone, 2 orange traffic cones and a tape measure.
