Creating Vector DataFor the USGS and NOAA photos Using ArcMap we: • Imported scans of the flightline diagram
• Georeferenced the flightline diagrams
• Added points, and assigned unique ids created during the database populating process
• Imported the spreadsheets (converted to DBFs)
• Using the unique ids in the dbf and the points, did a basic “join” to connect the data we created with the latitude/longitude information• export shape files

Creating Vector Data
Additional Step With USDA pictures • Remember these are Mosaics, not flightline diagrams
• So center points needed to be approximated first
• Using Photoshop, we manually created these center points
• Then imported that image into ArcMap
• then till all the other steps…

Lessons Learnt
•Data
-Do not purchase imagery without metadata! -Have a plan for access BEFORE buying the images -Be involved in all stages: planning, purchasing, follow-up, processing and interface building…
![Page 46: Hawai‘i’s Aerial Photographs: Creating a Visual Interface with Flight Diagrams by G. Salim Mohammed](https://reader033.fdocuments.in/reader033/viewer/2022060115/557c8ee1d8b42ab0788b53bb/html5/thumbnails/46.jpg)
Lessons Learnt
•Processing
-ArcGIS is VERY finicky and particular! -Document, document, document… -Be very open to changing how you process -Keep track of the details/implications -Accept a certain level of approximation
![Page 47: Hawai‘i’s Aerial Photographs: Creating a Visual Interface with Flight Diagrams by G. Salim Mohammed](https://reader033.fdocuments.in/reader033/viewer/2022060115/557c8ee1d8b42ab0788b53bb/html5/thumbnails/47.jpg)
Lessons Learnt
•Display, Access and Downloading
-Open source options out there – geoserver (shp files) -Jpegs versus tiffs – thumbs are important -reduce number of clicks – make it user friendly -Set it up for the long term – how can I display maps?
No amount of server space is enough!
