Overview

PDC

Project

ArcGIS

Data and Metadata

33

Provides proactive data for disaster managers

Identify disaster prone areas

Identify how disaster managers can help prepare for and solve the problems caused by a disaster

4

Project

Map Mile Markers for MauiTake GPS points for all highway mile markers on MauiRecord Hwy number, name, and take a picture of the marker

Useful for creating more accurate disaster maps

Ex. – West Maui fire(not the one in the pic but the recent one.)

Data and Metadata are collected and added to ArcGIS

What is GIS?

GIS = Geographic Information System

An organized collection of computer hardware, software and trained users designed to:

– Capture…– Store…– Update…– Manipulate…– Analyze…– Display…

Project stepsLearn ArcGIS

Drive and collect GPS points, highway name and number, and pictures for every highway mile marker on Maui

Load data into ArcMap

Write metadata for all the collected data

Re-project all GPS points using tool in ArcMap

Create file to load onto server

10

Data vs Metadata

Metadata describes data. It’s data about data.

Example: A photograph is data and the description written on the back is metadata.

Photographs of the markers and a short description make it easier to find the location again

Projection

Maps use projection to represent the two-dimensional curved surface of the earth. Different projections are more accurate in different areas.

The data had to be projected from UTM (Universal Transverse Mercator)1984 to NAD 1983 UTM Zone 4N. This was to bring the points collected from the GPS (in UTM 1984) into the same projection as the current maps in use at the PDC (NAD 1983 UTM Zone 4N).

16

Community Effect

Disaster planning helps protect and save the aina by preventing or quickly resolving disasters.

17

Conclusion

GIS helps PDC track and plan for disasters.

GPS waypoints of mile markers allows for more accurate disaster tracking and management.
