The state and county population projections data comes from the different state data centers. A cut-and-paste ready citation is at the bottom of the table.

Also, the 2007 population estimate data has been revised to the 2008 population estimate data. This data is in the Population Trends table, which is also part of the Socio-Ec Data Report. I know, I know…2008 estimate data is ancient. But it’s the most current population estimate data available for places (cities and towns) from the Census.

6 Best Sources for Local Land Use/Land Cover GIS Data

Co-written by Aaron Herman

Land Use Type: Hay/Pasture with Needle Present

Land Use Type: Hay/Pasture with Needle Present

Searching for land use/land cover data for your projects can make the proverbial needle in a haystack search seem like a walk in the park. At least with the needle in the haystack search, you know that the needle exists and you know where the haystack is. When searching for land use/land cover data, there may OR may not be local data, and you may OR may not know the agency that has the local data.

The best case scenario would be that your project/area of interest is in an area that has a local agency with excellent, accessible and current land use data and that they’ll let you have access to that data for free. I’d check the following agencies when hunting for land use data.

1 & 2. MPOs and COGs

I would start searching for land use data at the local Metropolitan Planning Organization or Council of Government (aka MPO & COGs). To see if there’s a MPO or COG in your area, check out this list of MPOs and COGs. When you visit their websites, search for “GIS”, “data”, “maps” or “land use.” A few tips when looking for MPO/COG data are as follows.

  • While most MPO/COG data is free, you may have to pay for some land use data as in the case with Metro, Portland’s MPO.
  • You may need to provide your contact information to the MPO/COG to access their data as is the case with the Central Texas Council of Governments.
  • You may also need to contact the MPO/COG for assistance in finding exactly what you are looking for, as is the case with the Tampa Bay Regional Planning Council. This MPO has links to server directories containing data, but the file names are not intuitive. There’s not a way to know exactly what is about to be downloaded.

3. Cities

Begin by going to your city’s website and searching for GIS data. If an initial search is fruitless, contact someone in the community development department, planning department or natural resources department to see if a land use dataset is available.

4 & 5. Counties and States

If an MPO, COG or city does not have land use data for your area of interest, try going to either the county or state website for information. The Des Moines Area MPO has a link that takes you to the Iowa Geological Survey’s GIS Library where you can search for and download data by county or by theme for the entire state of Iowa.

Another good starting point is simply doing a Google search for “state name+GIS”. Many states have a .gov or a .state.us site concerning GIS, maps and data. From these home pages, you will have to search for land use data. Not all states’ GIS portals are as easy to use as New Jersey, North Dakota, Oklahoma or Texas portals. Some states like Georgia require a user profile to access free data. You may have to dig a fair amount to find land use data from a state’s GIS page. Or you may be required to follow links away from a state page to, for example, an educational institution’s GIS department or a non-state-government-operated clearinghouse.

6. Geospatial One Stop

Geospatial One Stop is a GIS portal to help you get access to geospatial data. But don’t let the name fool you–I wouldn’t call it a One Stop. A better name might be Geospatial Another Site to Check on your hunt for land use data.

The Back Up Plan: USGS’s 2001 National Land Cover Data Set

And if all else fails, check out the USGS’s 2001 National Land Cover Data Set–a land use data set that covers the entire United States.

If you need more information about where to get land use/land cover data, Aaron Herman researched and wrote an excellent whitepaper on the subject. This blog post is based on his research. If you want a pdf of his whitepaper, contact me here and I’ll send it to you.

Do you know of other local agencies/organizations that provides land use data? Let me know about the agencies that I forgot to include in the comments below.

National Land Cover Data Set: when there’s no Local Land Use GIS data

Co-written by Aaron Herman

Finding land use land cover data is a pain. Unless your project is within an MPO/COG that has historic and current land use shapefiles that are easy for your GIS guru to access, you can be up a creek without a paddle when it comes to finding good land use data.

Despite the data challenges, many planners HAVE to have land use data for their projects. For example, over 90% percent of transportation environmental impact statements address land use impacts in their indirect impacts analyses according to this unscientific survey. So what should you do if your project is in an area that doesn’t have local land use data? Or what if you have a giant project area and the land use data set for one area doesn’t jive with the land use data set for another area?

USGS Land Use Data

If you can’t find good land use data from the typical local venues (I’ll blog about “typical local venues for land use data” next week), check out the US Geological Survey’s 2001 National Land Cover Data Set (or USGS NLCD 2001). The USGS 2001 National Land Cover Data Set is the latest, most accurate, nearest-to-complete and standardized land use coverage for the entire United States. Yup, you can get land cover data for the whole USA enchilada.

2001 National Land Cover Data Set

Positives of the USGS 2001 National Land Cover Data Set

  • Nationwide land use data for the entire United States
  • Standardized land use types makes for easy apples-to-apples comparisons
  • Have historic data & are working on more current data set (2006) for visualizing land use trends over time

There is a USGS NLCD 1992 data set. And the land use experts over at the Multi-Resolution Land Characteristics Consortium are working on a USGS NLCD 2006 data set. You can use these USGS National Land Cover Data Sets to visualize land use changes over time.

Negatives of the USGS 2001 National Land Cover Data Set

  • 2001 is old
  • National land use data won’t be as detailed or current as local land use data
  • The data is provided as a image. While it’s possible to convert the image to acreage estimates, it’s technically difficult to do and would involve custom scripting.

Head to Head Battle: Local Data vs. USGS 2001 National Land Cover Data

Generalized Land Use 2005, Twin Cities Metropolitan Council

Generalized Land Use 2005, Twin Cities Metropolitan Council

2001 NLCD Data

2001 NLCD Data

Let’s compare the land use data provided by Twin Cities’ Metropolitan Council and the USGS NLCD 2001. I was able to download Generalized Land Use 2005 data from the Metropolitan Council for the seven-county area. For comparison, displayed below is the USGS 2001 National Land Cover data for roughly the same area. These images are pretty small–if you need bigger images or want more information about land use land cover data sources, scroll down to the end of the blog post where you can get more information in a pdf.

You can get much more specified data with the local Metropolitan Council data set. For example, I can determine Single Family Attached versus Single Family Detached versus Mobile Homes using the Metropolitan Council’s data. The USGS 2001 National Land Cover data provides generalized data on Developed High Density, Developed Low Density and Developed Medium Density. But not every project area has good, accessible land use data like the Metropolitan Council data. And that’s where USGS 2001 National Land Cover Data comes in handy.

Bottom Line

If you have a small project in an area that has good local land use data, local data is your best bet. If you have a large project area (think multi-county, multi-MPO/COG, especially multi-state) or you can’t find good local data, then check out the USGS 2001 National Land Cover Data Set.

If you need more information about where to get land use land cover data, Aaron Herman researched and wrote an excellent whitepaper on the subject. This blog post is based on his research. If you want a pdf of his whitepaper, contact me here and I’ll send it to you.

Lower Prices + A New Way to Get More Data Faster from Cubit

Change“Change is inevitable – except from a vending machine.” Robert C. Gallagher

The What
This week, Cubit is rolling out lower prices and a new way to get more planning data faster. In the past, users purchased individual data reports for $249 per report. Now you can get unlimited data reports for as low as $20 per month. Check out the revised pricing page to learn more.

These are big changes for Cubit. Also, the look and feel of the website will be changing later on this week. You can reach us here if you want to yell at us or if you want to get your own Cubit account.

The Why
Cubit got it’s start when Kristen was frustrated by how long it took to get data for NEPA documents like environmental impact statements (EISs) and environmental assessments (EAs). Until a week ago, all of Cubit’s paying users were preparing EAs or EISs.

When Cubit offered $5 unlimited accounts for 2010 to raise money for the oil spill clean up, we assumed that the majority of the users who would sign up for a $5 account would be engineering firms and planners writing NEPA documents. Boy, were we wrong.

Private planning firms, MPOs/COGs, researchers, government agencies, non-profits, college students, professors and economists all signed up for Cubit accounts. In fact, users writing NEPA documents made up a very small, minority $5 account sign ups.

Boy, Did We Feel Dumb!
So here, Anthony and I have spent the past year talking to NEPA planners, marketing to NEPA document preparers, going to NEPA conferences and designing products specifically for NEPA work. And the majority of NEPA folks aren’t nearly as interested or excited about Cubit technology as some of the other groups that jumped on the $5 account offer. Boy, did we feel dumb!

Once we recovered from our surprise, we started asking non-NEPA folks who wanted Cubit accounts questions about what types of projects they were working on, what data they need and how they want to access and pay for Cubit.

What We Learned
A New Way to Get Data: What our non-NEPA users told us is that they’d prefer a model where they could get unlimited data reports. They wanted “a service that I can log into and access whenever” rather than a “buy one report here and one report there when I have a large project that needs data”. The old way of getting data was based on NEPA folks telling us that they wanted individual reports and needed to pay per report so they could charge the price of the report back to the project (don’t worry-we still offer $249 reports if you HAVE to charge the price of the report to a project).

Lower Prices: We heard that non-NEPA folks needed 2 price points: 1. a starting price point for users who have to pay for Cubit out of their own pocket, because “it’s too much of a pain” to get their companies or organizations to pay for Cubit and 2. a full featured price point for companies and agencies that want their employees to have access to Cubit.

In Conclusion
Based on these 3 lessons learned (1. non-NEPA users are even more excited about Cubit than NEPA users; 2. non-NEPA users want unlimited data access; and 3. non-NEPA users need 2 price points), Cubit is changing direction. Now, NEPA and non-NEPA users can get unlimited data for $20 per month or unlimited data plus advanced map features and Word documents for $60 per month. Learn more about prices and sign ups here. And over the next few weeks, we’ll be ripping out the NEPA-focused language and graphics on the website and talking about Cubit from a more general planning perspective.

I don’t want to end this post by saying something trite like “Thanks for your support as we make these changes”. I think “Please forgive our mess” would be more appropriate. So please forgive our mess. It would mean a lot to me if you’d give me a quick thumbs up or thumbs down comment below.
