My previous posting covers how to import data from ArcGIS via KML format because KML is the format that Google Fusion Tables accepts. Yesterday, I found a website, shpescape.com, which takes your shape file (.shp) and import it into fusion tables for you. This blog article is not really tutorial because the website is simple enough to use it. However, people who interested in how things work, I’m introducing the walk-through here.
How to pack files
- First of all, you need to prepare a zip file that contains your shape file and other related files. I have two sample shape files: U.S. States and Zipcodes. Your folder probably look like this.
Inside a folder
- Right click the folder and select “Send To > Compressed Folder” to zip them.
Create a zip file
Now, you are ready to upload those two shape files.
Make sure the file name is in lowercase. I tried to upload uppercase file name (e.g., STATES.SHP) and shpescape.com showed an error message. I sent a request to the developer so this might be fixed in the future.
How to uplaod
- When you click upload, it will ask you a permission to connect shpescape.com to your Google Fusion Tables. Login your Google Account and approve it. This is only one time setup.
- Click upload and select the .zip file from above.
- Sit back and relax. It’s queue system, so if there are other people using the importer, you have to wait for while.
- Once it’s completed, you will see the link on your Fusion Table ID number.
- There is 200 MB limit for Fusion Tables.
- When I imported all zipcodes data, it did not display entire points on the map. It displayed after few minutes. I guess there is an internal process going on.
In Fusion Tables
Polygon converts nicely
Conculsion – Exodus from ArcGIS Server?
Converting directly from shape file will motivate traditional GIS user to move to Web 2.0 world which make visualization much easier. Combination of shpescape.com and Google Fusion Tables could be strong competitor against some aspects in ArcGIS server standard edition.
I often see researchers publish their articles but not their data on internet because it requires a lot of extra work; such as, configuring a domain name, preparing website, etc… Google Fusion Tables totally remove those obstacles and it should help professionals to open their data without meaningless burden.
This type of webservice is quite useful but I imagine the CPU and their bandwidth might cost a lot as the number of Fusion Table user increase. I hope Google acquire their platform as a part of Fusion Tables.
