I will do flood risk mapping watershed and terrain analysis by gis


About this gig
Poor terrain interpretation, inaccurate watershed boundaries, or unreliable flood susceptibility mapping can lead to weak planning decisions, reporting issues, and costly mistakes in infrastructure, disaster management, or environmental studies.
You need GIS analysis grounded in hydrology, terrain interpretation, and defensible spatial methodology not just someone running tools in ArcGIS.
I help clients produce GIS outputs that support real decisions, including:
- Identifying flood-prone zones for planning and mitigation
- Understanding drainage behavior and watershed dynamics
- Supporting infrastructure and urban development studies
- Improving environmental and disaster risk assessments
- Creating publication-ready maps for reports, research, and presentations
DM me to know what i will deliver.
Before you order, send me your study area, available DEM resolution, and what decision this GIS analysis needs to support. I will tell you exactly what is possible.

FAQ
What data do I need to provide for flood risk mapping?
Ideally share your study area boundary (shapefile or coordinates) and any existing DEM data you have. If you do not have DEM data, I can source SRTM or Copernicus DEM for your area at no extra cost. The more context you share about the project purpose, the better I can tailor the output.
What software do you use and will I receive editable files?
I work with ArcGIS Pro, QGIS, and Google Earth Engine depending on the analysis type. Standard delivery includes high-resolution map outputs in PDF and PNG. Editable shapefiles, GeoTIFFs, and project files are available as a gig extra.
Can you work with my own DEM or survey data?
Yes. I regularly work with client-provided datasets including LiDAR point clouds, custom DEMs, and GPS survey data. Share your data format when you message me and I will confirm compatibility before you order.
How accurate will the flood risk map be?
Accuracy depends on the resolution of the input DEM. SRTM 30m data is suitable for regional-level assessment. For detailed local analysis, higher resolution data like LiDAR or Copernicus 10m DEM produces significantly more precise results.
Can this output be used in a research paper or official report?
Yes. My outputs are cartographically formatted with proper legends, scale bars, north arrows, coordinate systems, and data source citations - meeting the standards required for journal submissions and institutional reports.
