Extract surface Sample Clauses

Extract surface. The vertical projection method estimates DTM by finding the minimum z-value for all points within a given cell of a grid. This value is assigned to the cell, so the information about exact position of the minimum (maximum) point is not used. The Extract surface module extracts the point with minimum or (maximum) z-value for each cell of a given grid. The points with extremal z-values are saved to an output point cloud. The output point cloud can be exported to a GIS program and used to interpolate DTM or DSM. The surface interpolated from the extracted points fits well to the terrain (or to the canopy surface), because exact position of points is used in interpolation. Moreover, a spatial interpolation also calculates values for the grid cells, which are not covered by the point cloud. Example:

  • Drainage ▪ Prevent silt bearing road surface and ditch runoff from delivering sediment to any streams or wetlands. ▪ Maintain rolling dips and drivable waterbars as needed to keep them functioning as intended. ▪ Maintain headwalls to the road shoulder level with material that will resist erosion. ▪ Maintain energy dissipaters at culvert outlets with non-erodible material or rock. ▪ Keep ditches, culverts, and other drainage structures clear of obstructions and functioning as intended. ▪ Inspect and clean culverts at least monthly, with additional inspections during storms and periods of high runoff. This shall be done even during periods of inactivity. ▪ Perform preventative maintenance work to safeguard against storm damage, such as blading to ensure correct runoff, ditch and culvert cleaning, and waterbar maintenance.

  • Storage The ordering agency is responsible for storage if the contractor delivers within the time required and the agency cannot accept delivery.
