I am particularly interested in international projects and those focused on remote environments where there exists potential for interesting and meaningful analyses using GIS and remote sensing methodologies.

comment How to write Python script for spatial interpolation?
Do you have an initial script that is not yet working that you can share? Most users of this site will expect some initial effort before providing you with finished code.

comment How to highlight features on user click in Leaflet?
You'll have to link your features somehow - an attribute would be the easiest way (e.g. all features associated with a specific bridge get a 'bridgeID' of say, 3). This is more of a logic handling issue than a technical problem. If you're already using GeoJSON you're 90% of the way there.

comment Why does ArcMap drag and drop report “one or more dropped items invalid”?
+1 The distinction between a 'layer' and the underlying 'dataset' is very important.

comment Is a master's degree needed for a GIS career?
+1 for writing. Even if the field you choose is very technical (i.e. GIS), the ability write gives you a huge advantage. You might start your career digitizing roads, but nobody wants to do that for 30 years.

comment Estimating sunlight hours from slope, aspect, and latitude
You might consider using Area Solar Radiation (help.arcgis.com/en/arcgisdesktop/10.0/help../index.html#//…) if you're using ArcGIS. You can choose to use an entire year if you just want the total radiation. The input data requirements are simple. Though, I can't imagine that you would want to ignore latitude.

comment Creating Cluster “Zones”
Excel is not database software and is very limited in terms of its' ability to search data. PostgreSQL allows you to perform SQL queries (w3schools.com/sql/sql_intro.asp) on data across tables. In addition to this, Excel cannot store geometries, whereas PostGIS can. PostgreSQL runs on Windows just fine.

comment Creating Cluster “Zones”
This sort of problem is usually best handled using a database, especially if you intend to create queries utilizing multiple fields. Personally I would import all of the data into a Postgres database (including PostGIS to store the point geometries).
