Fun Exploration of KyFromAbove Data With Python and Other Tools
Ian Horn
The Kentucky From Above Program has acquired Imagery and Elevation Data for the Commonwealth since 2010. Over the past two years, we have transferred the data from a compressed version stored on FTP/Box.com to cloud-friendly formats (COG, COPC) on AWS via the Open Data Registry. This workshop will explore some Python notebook-based tutorials on accessing data from the AWS platform.
In addition, topics such as leveraging KyFromAbove Open Data using STAC, Titiler, and other tools may be explored.
Building a Dashboard from a Survey and doing Boolean Algebra
Vince DiNoto
How often have you driven down a highway and seen a historical marker? Reading the information is impossible? Relating the information to other markers is impossible.
- What did the maker say
- How does it relate to the community
- How does the marker relate to the overall picture of history
This workshop will explore from collecting information, building informative pop-ups, displaying information in a Dashboard, and using logic to tie components together.
The presentation will also explore some of the new tools available in Survey123, web mapping, and Dashboards.
Mapping and Positional Accuracy: What You Don’t Know May Hurt You
Ben Shinabery, Pete Croswell, and Demetrio P. Zourarakis
Land Surveying - With the recent adoption of drones into modern mapping, many geospatialists, including land surveyors, have the power to map small or large-scale areas with their thumbs. The ease of technology is driving not only drones, but also industry. Problems arise when land surveyors do not understand how to accurately locate or validate the data outputs. Furthermore, GIS industry may not understand the legal implications of practicing surveying without a license by flying their drone. Our workshop is for all geo-professionals interested in knowing and understanding how drones fit into the legal specifications of the land survey industry. This workshop will give information on the laws, policies, and even delve into practical ways of verifying the precision of the end delivered map.
GIS Professional Practice - A plethora of geospatial information is constantly created by the use of different geospatial technologies. The resulting accuracy of that information is often viewed as a quality implicitly or explicitly expressed in cartographic and visualization products created. This part of the workshop will deal with the topic of the degree to which adherence to different types of geospatial information standards is required in the creation of professional products that stand to scrutiny. Existing standards and specifications (e.g., ASPRS, USGS) for different data layers used by GIS professionals, their relation to metadata, authoritative/validated datasets, and their implications for different use cases will be discussed.
Project Management - Geospatial data here, there, and everywhere! GIS professionals, practitioners in all fields, and average citizens today are confronted with a wealth of spatial data from a wide range of sources: imagery, and data collected from satellites, aircraft, and unmanned aircraft systems (UASs), a.k.a. drones; digital GIS data from government agencies and utility organizations; special purpose map data from private companies; etc. Very often this geospatial data is made available without clear information about its content or quality. If comprehensive metadata is compiled, it is often not easily accessible, and users fail to consult it to understand the nature of the data they are using and its suitability for certain applications. Data quality concerns of most importance are related to some of the metrics addressed on the metadata (e.g., spatial accuracy, completeness, currency, etc.). GIS professionals must become more familiar with and aware of these standards and how they apply to different data products and projects. This workshop will introduce some key topics on the theme of the relation of geospatial data quality and standards, including:
- Brief tutorial on spatial reference datums and coordinate systems
- Explanation of key spatial data quality parameters
- Exploration of absolute versus relative accuracy, and how this impacts a collection and use
- Examples of different GIS applications and how they impact data quality requirements
- Overview of key professional on standards, organizations, and special data standards that they provide (e.g., ASPRS, FGDC, ISO)
- Practical issues in the collection and use of spatial data collected from UASs
- Recommendations for users in preparing specifications for data collection and processing, and for the use of special data from different sources
- A discussion on standards in relation to field data collection
