Would a GPS Help?

This article provides guidance on navigating through STC's geography data and census products. It explains how to choose the right census and product, select the desired format, determine relevant themes and geographical hierarchy, and find specific files. The article also mentions the availability of DMTI census files and highlights the benefits and challenges of using STC's spatial data.

  1. Would a GPS Help? Navigating STC Geography Siobhan Hanratty Atlantic DLI Training, Acadia University, 28 February 2003

  2. Five Questions to Find Your Way… • What Census and which product do I want? • What format do I need? • What themes do I require? • What geographical hierarchy do I need? • Which specific file do I need? Show me!

  3. Where Do We Start? Geography is not yet on the web • Start on the ftp site ftp.statcan.ca /geography/census2001/

  4. 1. What Census & Product do I Need? Chose a product subdirectory Census1996 Census2001 CARS Documentation Attribute Maps PCCF PCFC Concordance Geosuite Spatial (This is where the gems are) /geography/census2001/spatial/…

  5. 2. What Format Do I Want? Spatial It’s a matter of choice… what software is your patron using? MapInfo ArcInfo /geography/census2001/spatial/Arcinfo…

  6. 3. What themes do I require? Spatial Census Boundary Files Road Network Files Skeletal Road Network Files Ecumene (Population density) ArcInfo CBF RNF SRNF Ecumene /geography/census2001/spatial/Arcinfo/CBF…

  7. 4. What geographical hierarchy do I need? Spatial ArcInfo CBF National Provincial CMA Extra Which path do I take??? /geography/census2001/spatial/Arcinfo/CBF/provincial …

  8. 4. What slice of the geographical hierarchy do I need? CANADA PROV/TERR CAR ER FED Non-CMA/CA CMA/CA MIZ Terr. CMA CA CT No CT CD Rural UA CCS CT CSD DPL DA Block

  9. 4. What geographical hierarchy do I need? Spatial ArcInfo CBF Provincial National CMA Extra cd ccs cma ct csd da dpl fed er pr ua dpp ccs csd ct da csd ct da /geography/census2001/spatial/Arcinfo/CBF/provincial /da…

  10. 5. What specific file do I need? Spatial ArcInfo CBF Provincial ccs csd ct da Gda_10b02.zip Gda_11b02.zip Gda_12b02.zip Gda_13b02.zip Etc. /geography/census2001/spatial/Arcinfo/CBF/provincial /da/gda_13b02.zip

  11. Now What? Thanks, but that was a lot more confusing than I thought it would be! Why don’t I just get a DMTI census file from UT? I’ve heard they are easy to use…

  12. Oh. Yikes!

  13. Wow. I need a moment…

  14. DMTI Project files (.apr) available; ArcView-ready Individual files come as shape, no need for importing + 96 Census boundaries are paired with Census tables in .dbf format, ready for joining to spatial files Bundling is still a “challenge” Alternative route: IDLS STC + STC spatial data only; census geo rocks! + STC Documentation is at your fingertips - Organization still chaotic - Tables still have to be tweaked before merging Okay, Tell Me More…

  15. Is It Worth It? You bet! It gives research an entirely new dimension and, though there is new language, you still have two feet on the ground at all times. We promise!

  16. Making a Sandwich Where in the world are we and is that really PB over there?

  17. GIS is really about… Where… What… & X Location: e.g. Latitude & longitude Attributes: Palm tree cover, old growth, near Joe’s oasis

  18. Sounds Simple! Let’s Go! “Now, just hold on to your shopping cart, missy!”

  19. GIS is Much, Much More! • Data networks • Technology (software, hardware) • Data creators • Institutional arrangements • Policies and Standards • Spatial Data • Metadata • Users GIS Infrastructure

  20. “What” can be any spatially-referenced entity or phenomena.This means that a project can get out of control very quickly…. Why You Want More Lessons Especially if you don’t use the standard or compatible scale, data and projection in your project.

  21. Why You Want More Lessons Imagine a sandwich in which everything imaginable including drano was added in random order, dropped at heights varying from two inches to 30,000 feet (yuck, the pickle just came through the roof and onto the kitchen table---sort of), the mayo ended up in the living room and the bread in the backyard, and the chicken—well someone forgot to cook it.

  22. So Start Gently! Your first map doesn’t have to be that kind of disaster. We’re going to take a look at one concept today—layers or themes of a map. It is a great concept to see in action and will really help with the reference questions you get!

  23. You begin with an idea…
