1. Electronic DEM delivery (data) Dayne Broderson dayne@alaska.edu http://www.alaskamapped.org/ an all text no pictures presentation less than 9 slides

2. DEM DELIVERY OPTIONS We've got questions.. What do you have? How did you get it? What do you want? How do you want to get it?

3. Delivering data now SDMI Options available now: Web Mapping Services (WMS) Data extracts (Make Map) Download of DATA bundles (Scraps)

4. WMS Web Mapping Service - Bring the data automagically into GIS desktops - ArcGIS (layer file) - Google Earth (KML file) - SwathViewer - UDig - Many other common desktop GIS tools - or server clients - DNR's AlaskaMapper - SDMI's AlaskaMapped browse site - ArcIMS

5. Data Extracts Very simple interface for general public 1.Find an AOI 2.Click 'Make Map' 3.You've got a map! (basic jpeg +.wld or GeoTIFF)

6. Download of DATA bundles (Scraps) 1.Select AOI 2.Show Available Data 3.Select a particular data piece 4.Download a bundle containing: - original data (RAW) - provided metadata - additional products generated to make it usable - masks/footprints - ingested image - color balanced? - reprojected? - value added processing (we hope - but you get what we got plus more so you can fix it up to your needs)

7. DEM Delivery Options SDMI Browse Bundle download (show available data) pro/con user gets the raw/original data... which is not a unified/standardized format/product not a service you can integrate into your desktop clients WCS (Web Coverage Service) Would hope for similar benefits of WFS although it doesn't appear to be as widely supported/standardized as we would hope(?) - Who is using this yet? What clients/software can ingest it? Chips/Tiles Other Options....

8. Got DEM? What do you want? RAW, WCS, Grid, Other... How do you want it? Seamless style, Browse Bundle, WCS, Other... What are future delivery methods we should be considering? Make DEM - AOI extraction Offering reprojection, reformating and reassembling chipped data Web Service for value added products o Derivative products o Contours o Shadow layers Fairy dust delivery options --- any ideas?

9. We've got a survey Take it - Available online http://www.alaskamapped.org (go right there) http://ln-s.net/24HU this would be slide #8 which is less than 9 if you start counting at 0
