(And BTW, tomorrow evening, Wednesday, at the Tigard Library, there's a demo on 'Tigard Maps', whatever that means. I figured to attend and see if they have anything on westside seismology. Will report back if there's anything useful. http://www.tigard-or.gov/library/default.asp)
If this looks like an emacs org-mode outline, there's a reason for that. If it's too cryptic/terse, maybe I can answer questions. All in all, it was an hour well spent; there is a lot of material available in the app that I didn't spot with a quick look-see.
* TigardMaps presentation, 10mar10 at the Tigard Library
** Ties together city, county and metro databases
** Uses SW from ESRI, presentation via Map Optics
** Similar sites in the area
*** Tigard www.tigardMaps.com
*** Portland www.portlandmaps.com
*** Hillsboro hbmaps.ci.hillsboro.or.us/hillsboro
*** Sherwood www.maps.ci.sherwood.or.us/multimap/index.cfm
*** Beaverton www.beavertonoregon.gov/departments/gis/gis_maps.aspx
*** Or go to your city's site and search for 'maps' or 'gis'
(Gis: Geographic Information System)
*** Tigard's data updated daily, WashCo updates weekly
** Lots of discoverable material on the site
*** Start from an address (or partial address) or intersection
*** Searches can take several seconds
It's drilling through lots of data files to pull together the reports
*** Particularly useful if considering say, moving to an area
*** Much detail on specific houses (tax lots)
House/Lot dimensions, price paid, zoning, school dist, permits taken
out. Home owner info is hidden for privacy, tho' if you follow the
links to the county site, for instance, you may find they're not
suppressing that info. While trying to be 'transparent,' each
jurisdiction has its own policies on what they present and what
they hold back
*** City/county infrastructure
Maps detail bridges, traffic lights, street lights, etc
Planning bug-out routes?
*** Utility Work-orders
*** Crime detail not tied to specific locations to protect privacy
Crimes are tabulated within a 1/2 mile radius of a given location
and are further broken down by type. A second presentation shows
crime 'cluster's. Crime data is the rolling previous 12 months of
reports
*** 'Hazards' are shown for a property/area.
Hazards include seismic, flood plain, wildfire, etc.
*** Aerial photos
Not just Google satellite views, Metro hires aircraft photo surveys
every year
Tigard's page has some aerial photos from 1940. Way cool
*** Sewer lines are mapped but fresh water is not
The authorities are tighter with this data, presumably due to Homeland
Security sorts of issues
