GIS Mapping and Design


GIS and CAD Services Image
Existing data and digital aerial photography, combined with ground-level data collection using GIS, form the foundation for producing accurate site mapping. ESA Scheda’s photointerpreters have mapped wetland/upland boundaries, coastal boundaries, land use/land cover, and vegetation.  Vegetation mapping has included seagrass, CERP stormwater treatment area (STA) emergent and submergent vegetation, canopy cover/hurricane damage, NWI, and FLUCCS. These projects have entailed the use of various different photointerpretation (PI) keys and, in some cases, development and documentation of a new PI key.  In addition, we have completed regional groundtruthing efforts for land use/land cover, seagrass, oyster and hard bottom mapping verification (boundaries and photo signatures). 
ESA Scheda has the capability to employ Unmanned Aerial Vehicle (UAV) technology; these drones are utilized for site recon, specifically for aerial imagery capture for vegetative mapping purposes.  This solution provides a very inexpensive option to obtaining high-resolution geo-rectified imagery.  With this technology, we can fly below the tree canopy and still assemble a continuous geo-rectified high-res image, which can then be photo-interpreted for mapping and trend analysis purposes.  Our staff hold the latest FAA approvals for UAV operation and also carry insurance coverage for use of these UAVs.
