Download GIS shapefiles for the Sound Transit (Seattle) from soundtransit.org
Todays map project: after downloading the shape files from LA Metro, posted to ArcGIS. I didn’t do anything special with the data.
The below link is to the LA Metro website where you can download GIS data on their routes and stations.
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.
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.

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.
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:
8. ArcGIS will create 4 columns in the dataset: Point_X, Point_Y, Point_Z, and Point_M.
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.
