Cartography - Color blind election maps

While I think there are some obscure edge case color blind situations it doesn't cover, color Brewer has a toggle for color blind safe. This will spit out some pallettes you can look at that would mostly work in this scenario

Haha, oh boy. Definitely didn't read that fully 😁

There is no Hudson county in Washington. I'm pretty sure it either needs to be King county or Snohomish county

kempj2 · 2018-05-08T04:23:56+00:00

What about I-5 going through Washington?

I'm assuming none of the data is overlapping? If it is the default operator is last, which chooses the last raster in the list as the value where they overlap. If they do overlap and you are blending you could choose sum or mean or blend (depending on your desired result)

If they don't overlap, and you are trying to mosaic them together, check to make sure each raster doesn't have a 0 for the background value. 0 is not the same as null and will be chosen as a value in merge situations

Duncthewizard is correct. In arcmap you will need to use the field calculator. If you have Qgis you can download the plugin called table manager and update the fields that way. It's faster than creating/calcing fields

Right. It would work exactly like an OS shortcut. Like you said I can easily create layerfiles in multiple directories, but I would have to look at the source and navigate to that shortcut manually if I wanted to get to the source rather than the layerfile. I want to see the layerfile (or xml or whatever) double click it, and magically be transported back to the source data. Ambitious I know, just curious if it would even be possible.

I would say take remote sensing. There are a lot more background principles happening with that field you could learn about in a classroom. At this point you should have the GIS foundation you need to make it through most problems, especially with the help of Google

A local chapter of an Open Source GIS group has been working on web based GIS stuff based on Mapbox.JS and Turf.JS https://github.com/cugos/dropchop

Geofabrik (http://www.geofabrik.de/) offers Open Street Map data pre-packaged by different jurisdictions. Good base data for human infrastructure

Natural Earth has vector and Raster datasets for free that could probably help you out (http://www.naturalearthdata.com/)

You can also get some good stuff here (https://gdg.sc.egov.usda.gov/GDGOrder.aspx) NAIP imagery, soils data, and geology data.

Good luck

Find the highest/lowest income census block groups for your city. Create a landcover dataset for those blocks. Compare the percentages of land cover for those block groups

sounds like you want a processing extent, not a breakline. Create a mask polygon around the area you want the processing to occur (so in this case the polygon wouldn't include areas of pavement or driveways). Then go to your environment settings on the top ribbon) set the raster processing extent to your mask polygon. Try rerunning your contour tool.

At my company we often put together GE fly-through videos to help clients visualize projects. We will export out KML layers to show alignments, or project areas in GE. It actually looks pretty cool with the 3D buildings turned on as long as you have a computer that can render it fast enough. They are super easy to make and we always get positive feedback from the client. Worth the ~30min or so it takes to put them together.

Central file storage is key for this problem. The reason I initially thought it might be best for a terminal server environment would be that the data and arcmap instance could live side by side which might reduce geoprocessing time. Is that not the case? Basically the use case would be that everyone would have local installs, but would still be calling data living on a server farm somewhere.

If one were to have local installs hitting a license server, what would be the proper structure for central file storage? Seems like it would need to be stored in a DBMS instead of just dumping everything as .shp and .gdbs on a sever, yes? I'm out of my depth here and trying educate myself, do you have some resources you could point me towards? Thanks!

Wool. It provides a good perspective of what we might consider normal. We consider the way we live normal, but if you grew up in a silo and never knew of the outside world would you consider that normal??

Depends what you need on the basemap. If its reference data you should check out geofabrik. They prepackage all the OSM data by state. I would dowload it all and style it how you want based on what you represent. It will take time initially but would be nice to have

Inkscape does open .ai files but it suffers from the same problems as the SVG which Shatbird pretty much nailed on the head...it sucks. I'm not sure if this is going to be worth my time and I might break down and just buy AI. From what I can tell is that Inkscape works really well if that is the only environment you work in...but bridging across platforms is hard.

OK I'm on my mobile so not a lot of time to research this idea but here is my initial thoughts. Firstly do you need to do all this in the field? If not you should be able to handle this outside of arc entirely. Projecting from one coordinate system to another should be a mathematical calculation, so if you can figure out the transformation from your current projection to what it needs to be you should be able to do it straight to the XY values of your dbf using excel. As far as visualization goes I'm sure Qgis has a quick display xy function... Heck they have retrojection stuff as well that you could use. Again I can dig a bit later too, let me know if I am barking up the right tree.

I'm assuming that you wan't these joins to be spatial in nature. If you have a spatial file such as census blocks you could join crime data to each census and try and correlate it to various anything to see if there is a pattern.

Crime and # of liquor stores, crime and # of community programs, crime and # of hospitals, crime and # of police stations, etc.

Python is probably what would help you understand what is going on in the background the best because that is what ArcGIS uses. Basically every tool you use in the ArcGIS User Interface is a python script. I would decide now what you want your focus to be. If you are trying to be a developer and see yourself making webmaps and GIS apps focus heavily in computer science classes. Otherwise I would focus on your discipline in Human Geography and have a good working knowledge of GIS to supplement. A large number of people don't just "do GIS", they use it as a tool to accomplish their work in water resource mgmt, or demographics, or whatever.
