This is more or less a complete rewrite of my original answer; I was incorrect about what I thought the OP was asking. Given some of the additional information, I would recommend doing something like the following. You could enter it in the python console, or just make a standalone script on the desktop and run it with idle. import arcpy ...

In order to show isochrones on you system you can use the map api service iso4app. Currently is available for 3 countries: Great Britain, Portugal and Italy. More information at www.iso4app.net

One possible solution: Convert the polygons to lines using Vector > Geometry Tools > Polygons to Lines. (I am unclear if this creates closed polylines or individual line segments, which may be an issue later. If individual, you can dissolve/merge the resulting lines and not allow multipart features. If closed polylines you can use Explode Lines to get ...

You should use the Near GP tool for that (Advanced license only). It will add two fields to your point shapefile: one for distance to the nearest coastline feature and another for the coastline feature ObjectID.

Kostas, I reccomend using a SQL Query to determine the distance values from your road network. Generally, when I do this I will calculate minimum distance or average distance to the boundary points. In this case I am not sure what value exactly you are looking to calculate to determine your raster value. This calculation will provide the minimum distance ...

This is a fairly easy problem to solve if you just brute force it and doesn't require any automation. The question is basically a duplicate of Calculating all distances from single points to multiple polygons The key piece of information you need is an attribute in villages that defines which hospital they belong to. Since you've already generated Thiessen ...

Try using a Model to solve this Model Builder - Iterators - Iterate Feature Selection - this will allow you to go through each of your Locations one at a time and create individualized Euclidean Distance grids. Make sure you utilize in-line variable substitution so you are not writing over anything

When buffering (among other distance related operations) in a geographic coordinate system, your result may appear or be distorted in 2D because geographic is on a sphere/ellipsoid, not flat. Geographic uses angular degrees for measurement, and a degree of longitude can vary significantly in terms of distance depending on latitude (which is relatively ...

This service does what you describe in your original question - Given x/y coordinates of one city, it returns a JSON that lists only cities (not facilities) that are nearby the specified city, within a given radius (e.g. 100km) http://www.geobytes.com/get-nearby-cities-api/ As for an example - this link ...

First you need a line identifier. A buffer will probably do what you need, with dissolve. Then you can spatially join the buffer polys back to the points and transfer the buffer fid across. Then you need to sequence them in some way. The points all seem to go NE-SW, so perhaps ordering on the Y coord will get you a sequence. Apply this as an index to the ...

we have once Geoprocessing tool Point to Line in arcgis use once i think this is useful to you http://resources.arcgis.com/en/help/main/10.1/index.html#//00170000003s000000
