ArcGIS Online Atlas: Great Smoky Mountains N.P.

An online “Atlas of Great Smoky Mountains N.P.” I made for my final project in IS 590, GeoWeb technologies:
Environmental layers for Great Smoky Mountains National Park. Includes Environmental Protection Agency Level 4 Ecological Regions, 12 digit hydrologic unit watershed boundaries, temperature variances, trails, and forest threats (North Carolina only). Also includes waypoints for Appalachian balds (grassy areas at elevation)
There is an online map viewer where I added a DLIA logo:

HUC 12 watershed boundaries and interface to add layers.

I’m interested in adding it to the DLIA site to provide something fun and interactive for site visitors to play around with.
If I can figure out how to host KML versions of the species distribution models, it could also be useful for Park Service personnel as a quick reference that also has limited GIS capability.  There are also applications for biodiversity science and cartographic education.

PostgreSQL Database Application

Hi Chuck,

I am researching online mapping services for a class project and found this:

National Wild Fish Health Survey Database.

http://www.fws.gov/wildfishsurvey/database/nwfhs/

It runs on PostgreSQL. I don’t know a lot about PostgreSQL beyond that it is open source and competitive with MySQL and other enterprise-level database options. I’ve mentioned before it has an extension called PostGIS that allows excellent handling of spatial data.

So, seeing this application really caught my eye. I think it is a good aspirational model for what we could do with DLIA data. It appears to be all open source. Im copying out text they shared on <http://www.fws.gov/wildfishsurvey/database/page/about>

Major software components:

  • OpenLayers, an open source JavaScript library for displaying map data in most modern web browsers
  • MapFish, an open source web mapping development framework
  • GeoExt, a JavaScript Toolkit for Rich Web Mapping Applications
  • Ext JS, a cross-browser JavaScript library for building rich internet applications
  • GeoServer, an open source software server written in Java that allows users to share and edit geospatial data
  • MapServer, an open source development environment for building spatially-enabled internet applications
  • PHP, a free, widely used, general-purpose scripting language
  • PostgreSQL, an open source database management system
  • PostGIS, an open source software program that adds support for geographic objects to the PostgreSQL database
  • Smarty, a web template system written in PHP

I’ll probably explore this more, but wanted to share it with you now.
