Photogrammetry

Topographical mapping of ten County in the world, These projects was executed for full topographical map and DTM like Breaklines and masspoints with 5 foot Contour Intervals (CI) for the urban area and 10 foot Contour Intervals (CI) for the rural area. JV Geofocus team has extensive experience in photogrammetry mapping and have worked several hundreds of topo mapping projects in past.

LiDAR

Our technical/project team have executed several large LiDAR mapping and classification projects, below is a brief description of one of the initial project executed successfully. The total Project surface (area) is around 194 sqkm Lidar classification & 710 sqkm of Orthophoto generation. 194 Km2 of LiDAR bare earth classification is covered within the 710 Km2 of Orthophoto extent, where the client provided a less accurate DTM data for Ortho rectification only.

The input LAS data provided by client will be adjusted & auto classified which needs to be further classified based on the specification provided, The LiDAR bare earth classification is processed in order to meet 0.5 mtr contours.

Orthophoto

We have executed several large volume of Ortho Photo rectification projects over the years, the accuracy of the Ortho Mosaics we have generated has ranged from 5 cm to 5 Meter resolution. One of the major Ortho project executed covering an area of 4,000 Km2 for a company in India. We have also executed a huge DTM & Orthophoto rectification project for several clients across the globle.
