I'm follow the tutorial here and able to generate heatmap based on geocode. But I want is the heatmap color the map based on state of the country instead of geocode (Heatmap that based on the state boundary). The sample image like this. Does any python library was able to do this?
Just the information for those who search for this. Here have the tutorial about this. But you need to search the geojson file for your own country.

I am using Textrank method for extracting keywords from text and I am able to print individual keywords along with their scores. But I am currently trying to output whole text with the keywords I extracted earlier be highlighted (encircled etc).
I'm not sure who your target audience is, but I think the simplest solution might be to programmatically generate hypertext (HTTP), for example, where the keywords are given a foreground/background color of your choice. In fact, this can see this as being quite useful.
SpaCy has visualization tools but I believe they are targetted at providing specific NLP visualizations. I don't think they offer what you want, which seems to be a canvas for present information.
Oh! If you want to hack a solution, you can try this:
Create a custom entity type in SpaCy and have SpaCy report your keywords as your new custom entity type. Then you can use the SpaCy Entity Visualizer to highlight your entities.
My web-users need to know province\region names (administrative divisions) when they select a city, for example on Google Maps.
Unfortunately, Google does not have such info for some countries, for example for Afganistan, Pakistan, Uzbekistan, Tajikistan, etc.
I found GADM shapefiles and via QGIS I opened map and saw assigned names and coordinates of provinces\regions (This is the 1st time I work with maps).
I decided to combine Google Maps with data from shapefiles using coordinates from Google Maps in order to get names from GADM. I tried to google and found different python packages and documentations, but I can't find any information\code sketches about how to get location names from shapefiles using latitude and longitude.
Can anyone help me please with appropriate package/code which can resolve my issue?
I did not find a solution, where I can use shapefiles directly, but as a workaround suitable for me is to use GeoDjango, where shapefiles are imported to PostGIS. Anyway my project is Django-based.
For those, who does not use Django framework, can use just its shapefiles -> PostGis import module.

I have a geotiff that I have been working with in tilemill and I would like to select portions (buildings) in the map and create new layers as geojson objects. My issue is I don't know how to get the coordinates to create the objects!
http://chimera.labs.oreilly.com/books/1230000000345/ch12.html#_choropleth
this is a link to what I'm trying to do with states I just need the step where the coordinates are gotten because it doesn't seem to be in this document, they just give a shout to the guy who defined them. If anyone has done something similar to this, please give me a shout!
Update
I am not looking for the coordinates to the US, I have a fictional map that I am working from.
TileMill is a tool for visualizing data and creating map tiles - it isn't designed for creating or digitizing tasks. You'll want to export your map to Mapbox (or another MBTiles-supporting server), and use a tool like Mapbox's map editor or geojson.io to create GeoJSON overlays on top of it.
I have a KML file (NewYork.kml) which has assets listed in co-ordinates (inside LineStrings) in the New York region.
I am trying to pick a random point in New York (For example: 40.739974,-74.009605) and get any assets listed within a 500ft range.
I am working with Java/Google Earth API. Does anyone have any tips on which direction to go?
I'd recommend the geojs library, in particular the geo.Point class.
It has useful methods like distance() that you could use to see if two coordinates are within 500ft of each other.
I've created a Google map that loads a KML file as an overlay. It is a map of trailheads for say hiking. What I'm trying to figure out now is how to create a search that will allow visitors to search within the KML's data and show the relevant trailhead/s as results on the Google Map. Is this possible? I have a google search that will let them search for an address, but this does NOT search within the KML file's data for a trailhead.
Ideally the visitor could input an address, say 12345 Main st., Chicago, IL, or something and it would display results that are within a specified vicinity, say ten miles, of that address (ie latitude, longitude).
I'm a little lost as to even where to begin.
thanks for your help!

I don't know how often your kml file updates, but i recommend storing all the kml data in a database as well to make this easier. Maybe every once in a while re-download the kml file and update the database.
Then its as simple as using the haversine formula and searching the database for nearby trails.
What you're describing sounds like a good job for Fusion Tables. Fusion Tables give you a nice way to store and edit the data (even collaboratively). In addition, there are geospatial columns/data fields you can add (aka, a "Location" column that can be address or lat/long coordinates). Put all the trail heads in your fusion table and you can map them. Let people enter an address or lat/long, and you can query the fusion table to show all trail heads within the user specified distance of that point. See the tutorials to get started.
You can use KML search tool to do this. It supports KML KMZ CSV and GPX. You can find the tool here
