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 propose to develop a Python script to perform this task, querying the source data with SQL, then generating fresnel zones with a spatial algorithm, and writing out to KML.
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
