Looking for historical census data for your county or city in California? You might find what you are looking for at California’s Historical Census Populations of Counties and Incorporated Cities web page. The report provides total population counts for the state, counties, and incorporated cities in California from 17 decennial US censuses from 1850-2010. Make sure to read the notes and caveats about the data.
A scientist from NASA’s JPL in Pasadena says the long-awaited effects of El Niño will be felt soon in Southern California. Break out your kayak!
Just in case you have some extra change to spend on a Christmas present, check out the map auction at Swann Auction Galleries. There are a few deals!
Yes, El Niño is on it’s way to Southern California. This particular one will bring a colder than normal December along with above average rainfall. The following article states that this December it will start out dry, but the back to back storms will increase as the month goes on. The storms are projected to be between December 17-20 and the next set before or on Christmas. Click below to read more.
Here is an interesting article and map showing the largest employers in each state. Here in California it is the Naval Station in San Diego with 42,951 employees.
This map from the Tax Foundation uses data from the Bureau of Economic Analysis and answers the question state by state. In Mississippi, your $100 could buy $115.74 worth of stuff relative to the national average. On the other hand in California you would only get $88.57 worth.
A common, frequent complaint about Los Angeles is that it’s so big and so sprawly and it feels like it goes on forever. Is it really? Let’s get a better grasp of LA’s relative size, care of self-storage-focused site Spare Foot, which superimpose LA’s city limits over the borders of other major cities (and even a few landmarks). The pairings also show how LA compares to other metropolises in terms of land area, population, and density per square mile. Check it out.
Our ArcGIS Server licenses were going to expire soon, so I went ahead and updated them with new license files. All was well … for a while.
A week later one of our ArcGIS Server installations started having issues with the map services. Basically the map services, though running, stopped displaying the features that were in them. Looking into the error logs, we found stuff like this:
The Layer:’Parcel’ in Map:’Layers’ is invalid. The base table definition string “bur.ags.parcels” is invalid. No ArcGIS server license found. Contact your geodatabase administrator to update license
What? I updated the ArcGIS Server license! What is going on? Reading the error messages again, the part about “the base table definition string is invalid” reminded me about when I setup the Enterprise Geodatabase.
For this particular ArcGIS Server installation, I decided to setup the Enterprise Geodatabase inside PostgreSQL, store GIS data in it, and use the data for the map services. When I was setting it up I used the Create Enterprise Geodatabase tool. One of the parameters for the tool required me to provide a path to the keycodes file that was created when I authorized ArcGIS Server. I wonder if it is PostgreSQL?
Using ArcCatalog I tried to connect to the Enterprise Geodatabase in PostgreSQL, and here is what I got:
Aha! I guess PostgreSQL does not automatically get updated when I update the ArcGIS Server license. I am running ArcGIS Server 10.2, so the keycodes file (named keycodes) is located under C:\Program Files\ESRI\License10.2\sysgen. After entering that and pressing OK, I had access to the Enterprise Geodatabase again. I then restarted the map services that access the Enterprise Geodatabase and all was well again!
Surprisingly my other ArcGIS Server installation’s map services were working fine. However, they access an Enterprise Geodatabase in Oracle. I guess Oracle was updated automatically when I updated the ArcGIS Server license file? I don’t know, but if something similar happens, I will check the Enterprise Geodatabase first!
If you use ArcGIS Server with PostgreSQL, this little fix should help you if you encounter similar problems. -mike
Google Maps is now available offline. That means on your Android you can select an area to download from your phone and use it to navigate offline in areas that you don’t get good coverage in. And better yet, Google Maps can switch seamlessly between offline and online. Click here to read more.
