MidAmerica GIS Redistricting Workshop
When: January 15th, 2019
Where: Wichita, Kansas
In 2020 the U.S. Census will undertake the decennial counting of the population of the United States. Immediately following the result Cities, Counties, School Districts, and State Legislative bodies will begin the process of redistricting various election geographies in order to equalize the population that is represented by their political districts. Will you be ready?
This workshop is designed for GIS personnel, County Clerks, election commissioners, legislative research staff, and other staff involved in election administration, who will be involved in the redistricting process. This workshop is also suitable for any government personnel who are involved in the procurement of consultant services for redistricting. Please share this with anyone who fits the description.
Limited to 50 Participants
This class will examine the uses of local data within ArcGIS Online.
Attendees will learn:
Audience for this class could include: GIS Personnel new to ArcGIS Online, Appraisers, any other local staff looking to begin utilizing ArcGIS Online for their mapping and analysis needs as well as seasoned users looking for new ideas.
Cost: KAM Members $80, Non-Members $150
Location: Butler County Courthouse – East Annex Building, 121 S Gordy St, Suite 203, El Dorado, KS 67042 (316.322.4225)
Time: 9:00 a.m. – 4:00 p.m.

The Education Committee would once again like to know what topics KAM should prioritize for training opportunities this year. Please take this 2-3 minute survey so that we can plan the best training opportunities for you.
This class will provide a basic introduction to the popular QGIS Open Source GIS software. In this hands on workshop, we will look at adding in and styling data from popular formats including rasters, shapefiles, geodatabases, and CSV files. You’ll learn how to install plugins to perform various GIS processes similar to those found in ArcMap such as generating LiDAR contours, geocoding, clipping, merging, etc. Included will be adding in basemaps and printing maps to PDFs. Finally, we will look at other sources of tutorials available to further your QGIS education. If you have a laptop, please plan to bring it to the classroom pre-installed with QGIS; otherwise we may be able to provide one for your use.
This class will be held on Tuesday, August 8 from 8:30 am to 12:30 pm in the 2nd floor training room at 141 S Gordy St, El Dorado, KS 67042. Registration is $30 for members, and $70 for non-members. Snacks will be provided. Class will be limited to 15 participants.
Make the most of your imagery, LiDAR, and other raster data acquisitions. Raster data can be a bit mysterious, but it doesn’t have to be. With ArcGIS and a little know-how, you can leverage publicly available datasets and get more value out of your data purchases. In this hands-on workshop, you will learn how to:
The class will be held on Wednesday, June 28th, 9:00 AM to 3:00 PM at the Riley County Shops facility, 6215 Tuttle Creek Blvd, Manhattan, KS 66503. Cost is $30 for KAM members, $70 for non-members. Snacks will be provided, lunch is on your own.
This class will be held on May 16, 2017 in Topeka and will cover deed and legal basics, GIS editing, COGO, other advanced editing tools and some simple tool/script model building. Geared toward beginner and intermediate experienced mapping professionals. The cost of the workshop is $30 for KAM members and $70 for nonmembers. Registration is now open.

Raster data is an essential part of any GIS. From imagery to digital elevation models, rasters give context to our vector data, provide terrain measurements, and generally fill the void between lines. However, many practitioners never do much with rasters beyond displaying them as a background with the default symbology or performing a few basic terrain analyses. Learning how to work extensively with raster data can help you to leverage publicly available datasets and to get more value out of your imagery and LiDAR acquisitions.
Perhaps the easiest place to get started is to play around with imagery symbology. Adjusting the contrast stretch and gamma stretch can selectively highlight different features or make it easier to peer into shadows. It can even be beneficial to turn off the individual color channels to see things, literally, in a different light. To take your image symbology and interpretation to the next level, try out ArcMap’s Image Analysis window. This often-overlooked tool hosts a number of controls to quickly adjust the appearance of an image. The Image Analysis window also includes access to a variety of filters and raster functions for dynamic analysis and more sophisticated displays. Take the time to play around with how your imagery is displayed. You’d be surprised how much more you can get out of your imagery. Many of these tweaks will also improve the display of other raster data.
Some points of advice:
• Only change one parameter at a time, and in small increments
• If things start to look weird, you may have gone too far. Look for adjustments that are far away from the defaults. Sometimes it’s easier to start over.
• Play around! You’re not going to break anything, and who knows what you’ll find.
If you are interested in learning more about advanced image symbology or ways to get more out of your other raster datasets, I will be teaching a KAM-sponsored class on the subject in May. There is interest in hosting it in western Kansas, so if anyone knows of a suitable location, be sure to contact me at firstname.lastname@example.org. Otherwise, it will probably be hosted in Manhattan.

Planning for 32nd annual KAM conference is well underway with lots of educational and networking opportunities. The conference will be held in Lawrence, Kansas, at the DoubleTree by Hilton, 200 McDonald Drive, on October 17th – 20th. Starting with the pre-conference classes, we have a tentative agreement with Ken Wilkerson to teach an Introduction to ArcGIS Pro. Other pre-conference classes will be NG911 certification and Raster Analysis.
Keynote speakers this year will be Anne Wilson and Brian Obermeyer sharing their work on the Flint Hills Map project for use in schools throughout the region. Check the website for more information coming soon about their topic.
On Wednesday evening we will of course have our vendor’s night reception but with a fun twist, check the website often for updates. Thursday early evening will include a tour of the Bowersock Mill and Power Company. Then, dinner and drinks will be on your own in downtown Lawrence.
The map gallery competition will be brought back with prizes for 1st place overall and runner ups for hard copy map and digital presentation. Submissions will be open soon. When submitting a digital presentation, please also fill out a paper submission to be included in the project show off session.

KDOT is using some federal funds and tasked Professional Engineering Consultants, PA and Michael Dennis, RLS, PE of Geodetic Analysis, LLC to develop an integrated system of Low Distortion Projections (LDPs) for the state of Kansas.
What is a low distortion projection? Well, as a KAM member you are probably familiar with the Kansas North and South zones of the State Plane Coordinate System of 1983 (SPCS 83). Currently, when KDOT designs a road or a bridge, we survey in Kansas SPCS 83 coordinates, then coordinates are adjusted (“scaled”) to minimize the difference between projected (grid) distances and the actual distances on the ground. That difference is referred to as linear distortion, which must be accounted for in design and construction. LDP coordinate systems are rigorously defined to provide measurement distances close to true ground values by minimizing linear distortion.
Figure 1: Linear distortion in State Plane Coordinate System of 1983
What does this mean to the Kansas Mapper? You should get excited! If you are maintaining parcels, you can use the Kansas LDP coordinate system to reduce measurement error and rotation issues from plat records and surveys to GIS, and more accurately calculate the acreage of a parcel based on the spatial/shape representation. One of the main advantages of datasets defined in an LDP system is that they can be directly added to GIS without the need to rotate, translate, or scale – they are automatically correctly georeferenced.
As a Kansas Mapper, you know how to choose the most appropriate coordinate system to accurately display information. With these LDP coordinate systems, you will have new and improved options to consider. Look for more information soon about the LDP coordinate systems on the DASC initiatives site: http://www.kansasgis.org/initiatives/.
