Knoxville FOSS4G Meeting - May 19th 2017


May 19th 2017


This is Tennessee's first FOSS4G meeting.

It's an opportunity for Free and Open Source Software for GIS users in the area to get together and discuss projects (like Forestry projects, or small Gov't projects), software (QGIS, PostGIS, etc), and get to know one another. The event is free. We are looking for sponsors (we'll make you famous). If you want to present a paper please email Randal Hale ( and the group will get back with you ASAP. There are a limited number of tickets. So please reserve one so we'll know about refreshments.

If you want to speak email and the committee will get back with you.

List of topics and speakers in nor particular order.

  • Introduction to the FOSS4g Community
  • Introduction to OSGEO Live - TBA - s a self-contained bootable DVD, USB thumb drive or Virtual Machine based on Lubuntu, that allows you to try a wide variety of open source geospatial software without installing anything. It is composed entirely of free software, allowing it to be freely distributed, duplicated and passed around. It provides pre-configured applications for a range of geospatial use cases, including storage, publishing, viewing, analysis and manipulation of data. It also contains sample datasets and documentation.
  • What's New in QGIS 3.0 - Randal Hale - QGIS has undergone a massive rewrite. What I want to do is gover over QGIS 2.x and talk about migration to 3. I'll also be running QGIS 3.0 to show you what it looks like and some planned new features.
  • Landscape Level LiDAR Analysis for Vegetation Structure - Doug Newcombe - The State of North Carolina is in the process of collecting LiDAR data statewide at USGS QL2 ( 2 pts/meter) resolution or better. The point clouds generated from this effort can be more than 10 billion points per county. GRASS GIS can be used to quickly analyze massive LiDAR point clouds for canopy heights and other vegetative structure metrics that can be used to try to characterize habitat of different terrestrial species at a landscape scale.

  • LIDAR AND 3D Building Extraction - Carl Anderson

  • Extracting Landcover and Single Class Features from North Carolina NAIP Imagery - Frank Obusek - NAIP imagery is a readily available data set for most government GIS agencies and private sector organizations. Using 4-band image data, many types of landcover and features can be extracted without the burden of additional costs for each new project imagery. The leaf-on collection of the imagery lends itself to many forestry and vegetation-related classification projects. It can also be used to extract water-related features and quickly identify and geolocate water bodies of interest.
  • OpenStreetMap in Bradley County TN - Leah Keith Houle - Work on the Open Source mapping in Bradley County has been an ongoing project with the assistance of TeachOSM. Work and maps have been created for the Churches and Cemeteries of Bradley County. Mapping is continuing in this area for the Eastern Tribe of the Cherokee Nation and the Hiwassee Historical Museum for 16 sites of Fort Cass in the Northern portions of Bradley and McMinn Counties. To map the locations of the Fort holding cells and Blythe Ferry where 18,000 Cherokees that were removed from their ancestral land in the 1838 in the Trail of Tears from Bradley County. This is a work in progress with partners from the Eastern tribe of the Cherokee Nation, Cleveland Chamber of Commerce, the 5 point Museum and Hiwassee Historical Museum and Google Maps trails and Red Bank to create an interactive map with eventually and 360* video to show sites of removal.

PostGIS - Geoprocessing - Matt Brown - PostGIS can do lot more than just store and retrieve geographic data. In this demo I will walk through some basic geoprocessing tasks in PostGIS including buffer, union, reproject, and more.
