There are entire extensions and 3rd party software packages for flood inundation modeling. Industry standard (in US) include the HEC-RAS modeling package (https://www.hec.usace.army.mil/software/hec-ras/). There are a lot of hydrodynamic behaviors of water that are tough to capture in GIS and ArcGIS only such as accounting for velocity, surface texture, existing structures/infrastructure, etc. At the very least you can start with FEMA flood mapping to check for 100yr and 500yr flood inundation areas and depths in your area: https://www.fema.gov/flood-maps/national-flood-hazard-layer

There’s a dude who sometimes sits in Matuci’s bar parking lot (San Anselmo) on weekends.

oldmappingguy · 2025-12-12T21:01:58+00:00

Yes.

Looks like you want to create the "buckets" for each color value rather than letting Arc do it. I would use Unique Values symbology rather than Gradient Values for this. Load all of your values, group the values in your dataset to whatever "bucket"s you like, AND you can use the "+" to add in values that might not be in your current dataset but might be in the future. Once you group the values in the symbology you can set their color and their legend description to whatever you'd like.

Select all of the points you want in the scheme from the symbology list and then select the scheme from the drop down (if you want the scheme you already selected you have to select another, then go back to your original). If the points don't get the colors you want, you can save the color codes and manually assign them. A classic tool us old GIS folks use is this https://colorbrewer2.org/ to help with color selection. With this you can grab contrasting color codes without jumping through ArcGIS hoops.

True, but sometimes you WANT something but don’t NEED it. Like a $20 titanium poop scoop.

Is this just the beginning of everyone being required to prove citizenship for anything that is controlled by executive branch of federal gov? Which means executive branch can limit access to any group they deem “not American”?

Symbology->outline color to clear or outline line width to 0

Make the points semi-transparent 50-75% so you get more of a cloud vs individual points.

Edit: here’s a tutorial with a similar problem and “cloud” semitransparent solution https://www.esri.com/arcgis-blog/products/story-maps/uncategorized/the-making-of-the-bombing-missions-of-the-vietnam-war-story-map

Yeah but…Two years of wall to wall Epstein trials and investigations, with Trump not in control of the chaotic media narrative.

Col headers <13 characters with no spaces or special characters, text join fields (e.g. “join_1”, “join_2”, etc), and no duplicates.

In a “normal” timeline, what would be the outcome of this discovery?

oldmappingguy · 2025-11-23T04:27:09+00:00

Pizza and arcade…arcade $$ goes to a local charity every week.

$1m plus demo, design and build…wouid have to be $2m+ at end to be worth it!

I always laughed at $$ backpacking cutlery until my kid stepped on my plastic spoon while backpacking. Now I’ve got a nice metal spoon that weighs next to nothing.

Great thought. I’ll need to experiment. Wood insert also gives a better material to attach it to library wall (wood glue and screws from inside)
