Sound Transit GIS Files
Download GIS shapefiles for the Sound Transit (Seattle) from soundtransit.org
Los Angeles Metro Maps
Todays map project: after downloading the shape files from LA Metro, posted to ArcGIS. I didn’t do anything special with the data.

Mapbox Test
I got an invitation to try out Mapbox. It’s a pretty nice tool. I’ll have to see how it compares to ArcGIS Online.
Online Mapping
I now have an ArcGIS online account. I’m not sure what I will be posting on this mapping service, but we’ll see what I come up with. Right now, I’ve posted the bus and light rail maps for RTD Denver.
The background on the header that I created is a really old map of Fort Worth from 1876.
India Map, Map of India
MapsofIndia.com is the largest online repository of maps on India since 1998. The site provides business mapping solutions and thematic map images of India, its states, union territories, districts, and cities. It is an established brand, servicing businesses, institutions and individuals across the globe.

Adding XY (Lon, Lat) Coordinates to a shapefile
Problem: I have a point shapefile that I want to use with Tableau, but the data does not have X,Y or Longitude, Latitude in the dataset. What do I do?
Both ArcGIS and QGIS have the ability to add this data to shapefiles relatively easily.
Important: The point file must first be projected, otherwise the coordinates will not work with Tableau.
ArcGIS
My layer/dataset is called “fdia_eng_pnt”.
1. Open ArcToolbox
2. Goto Data Management Tools -> Projections and Transformations -> Feature -> Project
3. Pick your input and output datasets
4. for the Output Coordinate system, pick WGS 1984 (EPSG:4326).
5. Click OK
Once this process is done, the new layer is added to ArcGIS. Next…
6. Go to the Geoprocessing menu, then select Python. This will open the Python command window.
7. Type the following command (I know, so old-school…) and press enter:
arcpy.addxy_management("fdia_eng_pnt")
8. ArcGIS will create 4 columns in the dataset: Point_X, Point_Y, Point_Z, and Point_M.
QGIS
First, to reproject the data:
1. Go to Processing -> Toolbox.
2. In the toolbox, go to Geoalgorithms -> Vector -> General tools -> Reproject layer.
3. For Target CRS, select EPSG:4326
4. Run, this will create a new layer.
Here is a link to an app company called Fulcrum that has step by step instructions for creating the same columns in QGIS.
Once the columns have been created, you can export the dataset to a CSV that can then be opened in Tableau.
