This question already has an answer here:
I have downloaded this zipped shapefile of bus routes from the City of Houston data portal.
I then performed these steps in ArcGIS Desktop 9.3.1:
- Extracted the shapefile from the *.zip
- Added this shapefile as a layer to a data frame which has data in a coordinate system of
NAD_1983_UTM_Zone_15Nand noticed that it did not draw where I expected it to
- Used ArcToolbox>Data Management Tools>Projections and Transformations>Define Project to change its coordinate system to
NAD_1983_UTM_Zone_15Nand observed that it still did not draw where I expected it to
Can you explain why this shapefile may not be drawing in the expected location?
As background the properties of a shapefile that is drawing in the expected location is:
