Dear Sir/Madam,
I am a GIS developer and analyst with prior experience working on tasks such as this, from a background in environmental science and ecology. My skillset is fairly broad and includes working with ESRI ArcGIS, QGIS, GRASS etc; programming in Python and R; data management; spatial analysis; map design/cartography; web map development; and working with databases/SQL.
I use programming to solve most GIS problems, developing scripts using modules such as GDAL/OGR, GEOS, sp, pyproj numpy etc in Python or R, creating tools for geoprocessing and spatial analysis. In the past, this has included tasks like developing a Python library for hydrological modelling, similar to the flow direction and accumulation tools available with ArcGIS, but completely open source; extracting features from satellite/aerial imagery and DEMs; various zonal statistics and raster calculation tasks; shortest path routing using roads data and networkx; and an assortment of vector spatial intersection/joining tasks.
In this case, I can write a Python script using ESRI ArcGIS (arcpy), however will need further details in order to provide a detailed quote.
I will be looking forward to hearing back from you regarding this opportunity and discussing further. If you have any questions regarding my application, please do not hesitate to get in touch.
Kind regards,
Shaun
