Thanks for the introductory video. I know you mentioned you’ll be covering doing comparisons during the live session, but I’m wondering if you also be showing how to overlay other data, like from the census? When I work through the Brooklyn data, I’m interested in what might be gleaned from demographic data related to the trends that can be seen in the different ages, circ type, and zip code. Also, I’m wondering how other geographic data can be overlaid or inserted into the GIS map such as library branch locations and major transportation lines.
Thank you for the comment and questions. I will be showing how to overlay other data. Specifically, I am going to bring in census data to do exactly what you have commented. I will also bring in other geographic data, like roads, to show how any geographic data can be utilized to provide further analysis and make maps more informative.
Thanks for the video! I look forward to the session.
As a follow-up to Bruce’s question, I’m wondering if calculated fields can be done across overlayed data? I’m thinking of a map showing circ per capita.
I’m also interested in any tips you might have for using GIS for rural libraries. In our state, the majority are municipal libraries so any insights to mapping towns and villages would be appreciated. (Zip codes and census tracks are too big.) Libraries are interested in how neighboring communities using their library because funding is associated with this circulation, so it gets attention.
Thank you for the comment and questions. You can calculate fields across overlaid data, but it is a bit more involved in the GIS processing. I can show it better during the session on Monday than explaining in this comment, but it can definitely be done. I completely understand that census tracks are too big for many analyses. The Census also provides spatial data in the forms of Census Blocks and Census Block Groups, which are smaller than Census Tracts. I will be showing data during the session that is at the Census Block Group level. I hope this helps with your questions and I am excited to talk more during the live session.
This is fantastic, Zach. I took a GIS class in library school and applied some GIS mapping techniques to our library data years later. I consistently ran into issues getting my attributes and style information set up right but managed to map what I needed, but your webinar is helpful to show what I need to do next time.
I do have a question for detailed mapping. I have patron addresses that I would like to map over all the existing addresses in our library district (it is a school district.) Do you know where I can find a file of all physical (or postal) addresses in a school district? When I map patron addresses over our district map I just see population density (we have a lot of library patrons living in the most populated areas) but I’m missing the addresses of non-library card holders. Any ideas on where to find the shapefile I need?
I believe this was covered during the live session today. I am sorry for not seeing this question earlier. Data like that could be very difficult to find. You might be able to find data for it at the county level if they have a GIS team. Otherwise, it would most likely be a custom file that would need to be developed.
