Interactive coronavirus heat map shows spread of virus around the world
By Lurker,
Johns Hopkins University has put out a heat map in response to the public health emergency that updates the number of confirmed coronavirus cases across the world.
According to its website, the map was developed using data from WHO, CDC, China CDC, China National Health Commission and Dingxiangyuan – a website which reportedly aggregates data from Chinese government sources in “near real-time.”
As of Friday, more than 900 cases of coronavirus have been confirmed and 26 people have died
Huawei with Tomtom create mapping data as a Google Maps alternative
By Lurker,
With Huawei basically blocked from using Google services and infrastructure, the firm has taken steps to replace Google Maps on its hardware by signing a partnership with TomTom to provide maps, navigation, and traffic data to Huawei apps.
Reuters reports that Huawei is entering this partnership with TomTom as the mapping tech company is based in the Netherlands — therefore side-stepping the bans on working with US firms. TomTom will provide the Chinese smartphone manufacturer with mapping,

January 3, 2020 - Recent Landsat 8 Safehold Update
On December 19, 2019 at approximately 12:23 UTC, Landsat 8 experienced a spacecraft constraint which triggered entry into a Safehold. The Landsat 8 Flight Operations Team recovered the satellite from the event on December 20, 2019 (DOY 354). The spacecraft resumed nominal on-orbit operations and ground station processing on December 22, 2019 (DOY 356).
Data acquired between December 22, 2019 (DOY 356) and December 31, 2019 (DOY 365) exhi
How to install Web OpenDroneMap (WebODM) in Windows with Docker
By Lurker,
Interesting video on How Tos:
WebOpenDroneMap is a friendly Graphical User Interfase (GUI) of OpenDroneMap. It enhances the capabilities of OpenDroneMap by providing a easy tool for processing drone imagery with bottoms, process status bars, and a new way to store images. WebODM allows to work by projects, so the user can create different projects and process the related images.
As a whole, WebODM in Windows is a implementation of PostgresSQL, Node, Django an
Trump plan to encourage seafloor mapping
By Lurker,
The coastal waters of the United States cover an area dwarfing the nation itself. Yet more than half of that ocean floor is a blank—unmapped by all but low-resolution satellite imagery.
Now, the White House has announced a new push to examine these 11.6 million square kilometers of undersea territory. President Donald Trump this week signed a memorandum ordering federal officials to draft a new strategy that would accelerate federal efforts to map and explore these reaches.

GPS is an incredible piece of modern technology. Not only does it allow for locating objects precisely anywhere on the planet, but it also enables the turn-by-turn directions we take for granted these days — all without needing anything more than a radio receiver and some software to decode the signals constantly being sent down from space. [Chris] took that last bit bit as somewhat of a challenge and set off to write a software-defined GPS receiver from the ground up. As GPS started as a military technology, the level of precision needed for things like turn-by-turn navigation wasn’t always available to civilians. The “coarse” positioning is only capable of accuracy within a few hundred meters, so this legacy capability is the first thing that [Chris] tackles here. It is pretty fast, though, with the system able to resolve a location in 24 seconds from cold start and then displaying its information in a browser window. Everything in this build is done in Python as well, meaning that it’s a great starting point for investigating how GPS works and for building other projects from there. The other thing that makes this project accessible is that the only other hardware needed besides a computer that runs Python is an RTL-SDR dongle. These inexpensive TV dongles ushered in a software-defined radio revolution about a decade ago when it was found that they could receive a wide array of radio signals beyond just TV. source: Hackaday and GitHub - chrisdoble/gps-receiver
