A Catalog of Available GIS Data for Public Safety

• John Q. Murray
• Murray Information Services, Inc.

2
Collected data in 4 main areas

• Physical features
• What is there
• Roads
• How do we get there
• Ownership
• Who lives there
• Public safety data special needs
• USFS summer 2000 evacuation data, Firewise

3
Shapefile review

• A shapefile consists of several related files
• name.shp shape data
• name.shx spatial index
• name.dbf database file attributes data
• May also be other files name. (.prj, etc.)
• All files are required to display the shapefile

4
Shapefiles and location

• Top-level directory organized by county
  mineral.shape
• All data provided as shape files in a common
  coordinate system Montana State Plane NAD83,
  feet
• Subdirectories generally organized by the
  provider name epa, mtdot, nris, tiger,
  usfs...

5
Other directories

• mineral.shape / metadata
• Documentation who, when created where it is
• mineral.shape / 3xprojectsmineral.shape /
  8xprojects
• Learned (the hard way) that it is often handy to
  keep all project files in one place very easy
  to find them again
• Organized by ArcView 3.2 or ArcMap 8.1 projects
• mineral.shape / scripts (both Avenue and VBA)
• Scripts get reused on many projects
• Save scripts in text files here so they are easy
  to find

6
My file naming conventions

• Filename sometimes includes CS, units
• nad83ft.shp
• My convention filename prefix p or proj
  indicates that the data has been projected using
  the ArcView projection utility
• j indicates a join with other data

7
1. Physical features

• State of Montana NRIS (Natural Resources
  Information System)
• Political boundaries, PLSS (township-range-section
  lines), contour lines, lakes, rivers, streams

8
Physical features file location

• Under the directory mineral.shape
• nris - from the state of Montana website
• library - miscellaneous
• esrimt, esriusa - from ESRI, the company that
  makes ArcView 3.x Montana and USA
• usfs US Forest Service

2. Road data

• TIGER files U.S. census data
• U.S. Forest Service files
• Translation table between road numbers, names
• 2002 upcoming project, MDT
• Missoula Co. Surveyors office
• Full description of road data in the Network
  Analyst presentation

10
Road data location

• Mineral.shape/tiger
• Tgr30061lka.shp (meters), projTgr30061lka.shp
  (feet)
• Mineral and Missoula road data combinedprojMinMs
  laRoads.shp (feet)
• (Also have Sanders County, Lake county road data
  to produce large area maps)

11
TIGER website at NRIS

• Select shapefiles in Montana state plane
• Select counties

12
Mineral County Tiger roads

• Tgr30061lka
• CFCC road type
• FENAME road name

13
Use the provided Tiger legend

• Edit the legend
• From the Legend Editor, click the Load button
• Select the Tiger .avl file Tgr30061links-legend.av
  l, OK
• Click Apply

14
3. Ownership

• State of Montana cadastral project
• Location mineral.shape/cadastral
• Metadata mineralallje911.shp.xml
• State ownership joined with Mineral County E-911
  database
• Shapefiles mineralallje911.shp (meters),
  pmineralallje911.shp (projected to feet)

15
Ownership example

• Click on the property, all data is available

16
4. Public safety data

• At risk population special needs
• USFS evacuation data, summer 2000
• Access 2000 form
• George, Liz Gupton
• Frenchtown Fire volunteers data entry

17
Public safety example
18
Public safety data location

• mineral.shape/usfsevac
• usfsevac2000-mtnad83ft.shp (feet)
• usfsevac2000-mtnad83m.shp (meters)
• Currently 1,761 data points, latlon only
• Data entry from paper forms in progress
• Will do a table join when it is complete

19
Two deliverables

• On paper large-format maps and map books
• Gallatin County uses 11 x 17 black white format
• 3D color images for people who cant read topo
  lines
• Black and white / topo lines best if making
  copies
• On line data CD, training on using ArcView
• More versatile can create custom views as needed
• Can add more data as it becomes available
• Can tie in with E-911 auto-dial during evac event

20
Metadata

• Information about information
• Date collected
• Who collected it and why
• How long it stays fresh
• Coordinate system, datum, units

21
Metadata templates built into 8.1

• ArcCatalog has nice editing capabilities

22
Deliverables

• June 1, 2002
• CD with all current data, doc to Wayne, Kevin
• Map books in 11x17 format
• 3D color wall maps (detail of Saltese,
  Haugan/DeBorgia, St Regis, Superior, Alberton,
  larger area maps)
• Update CD When evac data is available
• Update maps Monthly as corrections arrive

23
Whats beyond June 1

• Weve started collecting data
• Raises a whole new set of issues
• Who has the latest data from the county?
• Who is responsible for correcting bad data?
• Who identifies the need for new data?
• Who coordinates with state, federal government to
  get their latest data?
• Are we legally liable for inaccurate data?

24
