To change the basemap, click the button next to the “Menu” button. Basemaps I usually use are:
USA basemap
ESRI scanned topo USA
Open street map
3/ To turn on geolocation tap Menu > My location.
A symbol will appear and follow you as you move.
Tap that symbol to see your coordinates and accuracy value.
4/ To make your own custom map link:
a) Make the map look on your screen the way you want it to look when it opens.
b) Click Menu > Link to this map
5/ To turn on other GIS overlays click the basemap button (next to the “Menu” button).
Look under the “Overlay” heading - mobile users scroll down.
Click an overlay to turn it on and again to turn it off.
6/ An overlay with a number in front is ‘on’. The highest numbered overlay is *on top*. Only the top overlay is clickable.
7/ Clicking the top overlay will display all the attribute data the GIS server has for the thing that you clicked. Sometimes attribute data will include a *link* that leads to more information.
8/ To see the fire weather forecast:
a) Turn on overlay “NOAA fire weather forecast”
b) Click the map anywhere.
c) In the attribute display, note the STATE ZONE
d) In the attribute display, click the link
9/ e) Add the letter “Z” to the STATE ZONE and search (ctrl-f) the page that appears on the result.
Example: If the STATE ZONE is CA221, search on CAZ221.
10/ The map updates the MODIS/VIIRS data at the top of each hour but only if there is new data on NASA’s server. You will need to re-open the map to see new data. Usually new data appears on NASA’s server 5-7am and 5-7pm
11/ The red/black perimeter uses data produced by the analyst that reviews infrared data for a specific fire and will only appear on the map for that fire.

1/_ Calling 911 with a cell phone to get help? They might not know your location unless you tell them! FindMeSAR.com (I am developer) is a web page that uses the GPS in your phone to display your coordinates and accuracy value. #SearchAndRescue#DebrisFlow
2/_ Use it like so:
Browse to FindMeSAR.com
Tap “Next format” until the yellow screen appears
Wait a few seconds for the accuracy value to get to 30 feet or less
Tap ‘Stop” #EmergencyManagement
3/_ The yellow screen displays your location in latitude longitude, decimal degrees. Every 911 call center understands that coordinate format.
There is an icon you can save on your home screen.
1/_ Interactive #GIS map showing risk of #DebisFlow for wildland fires. For the legend and to get the most benefit from the map, please click “Map tips” in upper left corner. To search on address click Menu > Search. #CAwx
2/_ The map opens at the #CZULightningComplex. You can pan the map to other 2020 fires and see the same type of data. Be patient! The map might be slow to refresh. It depends in part on how much other work the GIS server is doing.
3/_ The map can display the risk of debris flow for fires back to 2017. Here is one way to make a map to see the risk of debris flow for a fire prior to 2020:
A. Click the basemap button and look under the “Overlays” heading
B. Click “Turn off all overlays”
1/_ Trump does not own Mar-a-Lago and is prohibited from living there by the 1993 agreement he signed and permits issued by the City of Palm Beach. See thread for links to source documents.
**I will post unroll link.**
2/_ In early 1993 Trump was the sole owner of Mar-a-Lago. He filed an application with the city to convert it into a private club since he was in financial trouble and the cost of upkeep was high.
3/_ Chronology
March 1993 - Application for a Special Exemption Use and Preservation Plan
April 1993 - Addendum to the application
November 1993 - Use Agreement
1/18 Yesterday @gregolear published an article by @ThatShockratees which has the potential to be a game-changer for the senate by preventing Mitch McConnell from stonewalling the Biden agenda.
This thread provides additional analysis, clarification and citation to authority.
2/18 I have gone full circle from endorsing the idea, to expressing great skepticism and, after additional research, am back on the endorsing side. My compliments to @ThatShockratees
The analysis below *assumes* Rs retain the senate majority.
3/18 The published article talks about two things.
1. Delegation of the task of presiding over the senate. 2. Decisions by presiding officer as to which senator is recognized to speak.
1/7 This tweet thread describes the authoritative USA county-level *daily count* COVID-19 data that is hosted on my server and which can be used by anyone for any non-commercial purpose. #COVID19#COVID#CovidData
2/7 #JohnsHopkinsUniversity is widely regarded as one of the primary sources for authoritative COVID-19 data. Hopkins curates this data from various sources and hosts it on GitHub at github.com/CSSEGISandData…
3/7 The #JohnsHopkins “timeseries” data is a *cumulative count* of cases and deaths. My code automatically runs each night and converts those cumulative counts into *daily counts*. I am hosting this daily count data in separate csv files per month.
1/14 I have been volunteering to produce online wildland fire maps for about the last 10 years. This is a multi-part tweet to help people understand satellite hotspot data for wildland fires.
2/14 The #1 thing to know is that any fire data you see on maps is **not real time**. After a satellite pass it takes NASA ~3 hours to process the raw data before it can be displayed on any map.
3/14 Since data you see via an online map is **not real time**, never rely on any map (or anything else) to ignore an order to evacuate. The professionals that make decisions which areas must evacuate have more information than is available to you.
