Location: California
State of California - General Notes
Santa Barbara
- Dan Ancona was at
UCSB working on connecting the VTP to the
Alexandria Project, and part
of the work includes a model of UCSB
- see ADEPT DE
development plan - near-term objectives are to create a detailed,
navigable in real-time model of the South Coast region (defined as
approximately Point Conception to Carpinteria)
San Francisco Bay Area
- Data
- Bay Area Mapping
Association: BAAMA
- non-profit, professional organization that organizes bi-monthly
educational forums, the annual California GIS Conference, and periodic
technical tours on a broad range of geographic information systems (GIS)
and automated mapping topics including:
- regional data sharing, metadata, guidelines and standards for
digital data
- photogrammetry, web-based GIS, wireless GIS
- Google 3D Warehouse Cities in Development:
San Francisco
- San Francisco Urban Forest
Mapping Project
- Released in 2007, digitally pinpoints the location of each tree,
maintains tree data in a consistent database, and offers web access to
the tree data (via a MapGuide Open Source web interface).
- the S.F. Bike Map project
(now defunct)
- was a Java application for finding the optimal bicycling route
between the hills of San Francisco, with route directions, route maps,
and an address finder
- it would be great to do this sort of app in 3D, especially in places
like SF where slope is a major factor
- the story from author Trevor Smith, as of 03.07.23:
"The SF bike map project was originally going to a web application as
part of the San Francisco Bike Coalition
web site
but during the shuffle of leadership over there they lost interest in
it. So, I packaged up the renderer and route finder into an executable
jar. It works, but isn't the prettiest UI you've ever seen. There's a
sourceforge project
where you can get the source and the executable jar. The map data that
is in the repository is just the US Census TigerLine data combined with
the USGS elevation maps for San Francisco. It could do with some work,
too."
- there was an existing product: Virtual San Francisco (see
Virtual Tourism) which produced 3D
models of a large number of SF buildings, but the company went out of
business in 2003
Palo Alto
-
The
City of Palo Alto is the site
for a PRT study by Cities21 which
could leverage the VTP for visualization
- GIS Data
- there is a "citywide GIS Technical Advisory Committee" mentioned in
this
City Manager Report, but otherwise very little about GIS on the city
website
- a San Francisco company called Geodesy has been "instrumental in
the development of the city's GIS applications" and has a contract
to further integrate the city's GIS, Utilities CIS, and CADD
projects.
- their data is maintained as "OGIS compliant standard blobs in a
relational database" by "Encompass", which is a set of ActiveX
components created by Geodesy
- the blobs can be translated to GeoMedia or ESRI formats, but those
formats do not allow for the complete storage of all of the information
- conversion to ESRI SHP files on 02.01.09, resulting in:
- Built Features, 3 layers
- blb_3.shp should be importable into VTBuilder as building
footprints
- Road Features, 26 layers
- Transport Centerline, 4 layers
- tcrd_2.shp should be importable into VTBuilder as road
centerlines
- coordinate system is California State Plane (zone 3)
- coordinate problem: CA Zone 3
meters vs. feet
- Imagery
- have available two aerial photos, from 1999 and 2000, licensed and
non-redistributable, not georegistered at all
VTP Demo Area in 1999: Santa Clara, California
-
acquired
USGS 30m DEMs, free download from BARD
(Bay Area Regional Database)
- a BT was extracted using
VTBuilder
- a road map for the city of Santa Clara was created using
VTBuilder from USGS DLG
files (milpitas, sanjose-west)
- VTBuilder was also used
to correct the number of lanes and set the direction of traffic flow for
each road segment, which is used by Enviro to display proper road striping
- a corporate headquarters was modelled in 3DS MAX and brought into Enviro
- vehicles were added to the roads, using a simple network-traversal
algorithm for autonomous
Southern California
- AIS Terrain Team
created a model of
Los Angeles
- meant for use in police/military training and simulation
-
the
UCLA UST (Urban Simulation Team) has
modelled many parts
of Los Angeles
-
downtown, the Pico Union district, El Pueblo,
Mid-Wilshire, Wilshire-"Miracle Mile", LAX, Westwood, UCLA, Hollywood
Blvd. and Vine St., MacArthur Park, Playa Vista, and a portion of South
Central.
- CyberCity AG has a commercial
3D model of Los Angeles
- includes many datasets, including ground-level textured model,
auto-textured building models from stereo aerial photos, true
ortho-photos, and a 1m DTM
- Mojave Desert Ecosystem Program
is a GIS Data Clearinghouse which has:
- DOQQ and 100k DRG in TIF format, DEM in E00 format
- 100k vector data: boundaries, hydrology, transportation, vegetation
in E00 format
- 30m Landsat5 from 1993, which appears to be neither color-corrected
nor georeferenced?
- in BIL format
- really large files (>300 MB)
- Google 3D Warehouse Cities in Development:
Los Angeles,
San Diego
Emeryville (Bay Area)
- rapid change in the past 10 years means that finding accurate digital
data is a challenge
- USGS Quad: Oakland West, NE DOQQ
