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”

Open #GISsurfer map: bit.ly/39Y5BRA 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.

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.

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.

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…

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.

1/6 I’ve been volunteering to produce online wildland fire maps for about the last 10 years. The #1 thing to know is that any fire data you see on maps is **not real time**. There are 2 MODIS satellites and 2 VIIRS satellites. #GlassFire #GlassIncident #ZoggFire 2/6 The MODIS/VIIRS satellites make a total of 8 passes per 24 hours. For the West Coast very rough timing is midnight to 3am (4 passes) and noon to 3pm (4 passes). It takes NASA ~3 hours to process the raw data before it can be displayed on any map.

1/9 Here is a tip that can save a life (yours?) in an emergency. When you call 911 they might not know where you are unless you tell them. I developed #FindMeSAR as a public service project to help solve this problem. #SearchAndRescue #EmergencyManagement 2/9 #FindMeSAR (findmesar.com) is a webpage that uses the GPS in your phone to display your coordinates and accuracy value. Several coordinate formats are supported and each one has a different colored screen.

1/9 What happens if the #ElectoralCollege vote is a tie? Here is a website that lists 64 different ways that could happen:
270towin.com/electoral-coll…

If there is a tie then we might wind up with President Biden and Trump’s running mate as Vice President. 2/9 In case of #ElectoralCollege tie the 12th Amendment says the House elects the President with each state getting *one* vote and the Senate elects the Vice President with all 100 Senators voting. Link to 12th amendment:

1/4 If you zoom out any of the fire maps I post then you will always see all the current satellite hotspot data. That data is automatically updated several times per day. MODIS = red triangle. VIIRS = orange square.

Open #GISsurfer map: bit.ly/3h8oKCF 2/4 Caution! Satellite hotspot data is *always* several hours old when you see it on a map and locations are approximate. Never rely on any map to ignore an order to evacuate!

1/6 Here is one of my public service projects that might help to save a life. #FindMeSAR (findmesar.com) is a webpage that uses the GPS in your phone to display your coordinates and accuracy value. #SearchAndRescue #Hiking #10Essential 2/6 Several coordinate formats are supported and each has a different colored screen. The yellow screen displays your location in latitude longitude, decimal degrees. This format is used by all 911 call centers.

1/7 Each day #JohnsHopkins publishes *cumulative* counts of #COVID19 cases for each county in the USA. As a public service I wrote code to convert that cumulative count data into *daily* counts for all USA counties. #CovidData #Covid19Data 2/7 This daily count data is in one csv file per month. There is one set of files with daily *case* counts and another set of files with daily *death* counts. Anyone can download and use this data. The only limitation is no commercial use.

1/5 Here are links to csv files with *daily* counts of new #COVID19 cases and deaths for all USA counties. These daily counts begin March 24 and are updated each night just after midnight Pacific time with the counts for the prior day. #CovidData 2/5 Each day #JohnsHopkins publishes updated timeseries *cumulative* counts of new cases and deaths for all USA counties. As a public service I wrote code to convert that cumulative count data into *daily* counts. Non-commercial use only.

1/4 Each day #JohnsHopkins publishes updated *cumulative* counts of #COVID19 cases for each county in the USA. As a public service I wrote code to convert that cumulative count data into *daily* counts. This daily count data can be used for any non-commercial use. 2/4 The daily count data is in one csv file per month. These files include a latitude longitude centroid for each county and will be easy to import into spreadsheet or #GIS software. Each night the count of new cases for the prior day is added to the current csv file.

1/2 #JohnsHopkins is doing a great job posting *cumulative* COVID19 case counts. I developed code that runs each night and converts that data into *daily* counts of new cases. Anyone is welcome to download this data and use it for any non-commercial purpose. 2/2 The daily counts of new COVID19 cases are in one csv file per month starting March (data starts on the 24th). Below is an example download link.

1/4 Are COVID-19 cases/deaths increasing or decreasing over the last 14 or last 7 days in your county or state? This interactive map uses authoritative data from Johns Hopkins to give you the answer. Need help? Click “Map tips”.

Open #GISsurfer map: bit.ly/2Vr25Jk 2/4 Each location on the map has two symbols. Circle = prior 14 days. Triangle = prior 7 days. Red = count is trending up. Green = count is trending down.

1/4 Are you a #bored #student or #teacher? Do you like #maps #geography #GIS? Consider taking a look at #GISsurfer which is a general purpose web map I developed. This project is a public service and part of my way to “pay it forward”.

Homepage: gissurfer.com 2/4 Government agencies host all kinds of GIS data. Anyone can use GISsurfer to look at that data almost as easy as you surf the internet. No GIS savvy required! You can add GIS data to the map and then save a link that will display your map.

1/7 Curated list of 3,500+ government #ArcGIS server addresses. All links tested once per week and bad links fixed or flagged. These are ArcGIS servers, not 'portals'.

The “SSL problem” tag in the curated server list means Firefox found something wrong with your SSL certificate.

1/7 Short series of posts to help you understand the satellite hotspot data that you see on fire maps. Number 1 rule: Never rely on any map to ignore an order to evacuate. If you are ordered to evacuate you need to collect any pets you have and be gone.
#KincadeFire #GettyFire 2/7 There are three satellites that collect hotspot data, 2-MODIS, 1-VIIRS. Usually any given fire will have a total of 4-6 ‘looks’ per 24 hours. It usually takes NASA ~3 hours to process the raw data before it can be seen on any map. Thus, it is *never* ‘real time’.

1/4
Anyone can make their own custom #GISsurfer map to see near real time wind data.
1. Open GISsurfer with no layers bit.ly/2pfeMtq.
2. Drag and zoom to your area of interest. Or do Menu ==> Search
#DiabloWind #DiabloWinds #KincadeFire #TickFire 2/4
3. Turn on one of the wind gust or wind speed layers. Click the basemap button (next to “Menu” button), look under “Overlay” heading (mobile users scroll down), click layer to turn it on/off.
4. To stay oriented, turn on: ESRI roads and labels, County, State boundary.
