1/4 Why is perimeter data on the #Inciweb fire map out-of-date? The Inciweb map simply displays perimeter data that is hosted on the GeoMAC #GIS server. Why doesn’t the GeoMAC server have current perimeter data? #WAfire #ORfire #CAfire #AZfire #COfire #MTfire #GeoSpatial
2/4 For most big fires there usually is a nighttime overflight with infrared sensing gear. Experts analyze that data and determine a new fire perimeter. They also determine areas of intense, scattered and isolated heat. That data is then hosted on the public NIFC FTP server.
3/4 That new fire perimeter eventually shows up on the GeoMAC server and will then appear on the Inciweb map. The problem is that it seems to take a day or more for that perimeter data to go from the NIFC server to the GeoMAC server. Surely that process could be speeded up.
4/4 Below is a link to the fire map I produce. Red/black line = perimeter data from NIFC server based on last night’s infrared flight over the #WoodburyFire in AZ. Yellow cross hatch = perimeter data from the GeoMAC server.

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.** Image
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

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.

The key is #2.

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 Image
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.

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.
3/6 Usually by 7am pacific time the maps are showing all the MODIS/VIIRS data that is available until sometime after 3pm. Hotspot locations are approximate and sometimes the data is ‘false positive’.

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 Image
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.
3/9 The yellow screen displays your location in latitude longitude, decimal degrees. This format is used by all 911 call centers.
