  2. i only can thing one way, make direct edit on the database, adding the coordinate on the table rarely using qgis, but is it possible to make direct editing on qgis? if qgis capable to do such thing with postgresql, seems there is a way, but im not sure
  3. Last week
  4. Thank Lurker, It is also useful to me!
  5. Hi, I have two layers of polygons (gaps in the city) with unique IDs and smaller "lots". These gaps are dissolved from these smaller "lots" polygons (in some cases one lot is equal to one gap). These smaller polygons have the same ID (all ID1 lots - creates one ID1 gap). I have three types of these smaller lots polygons, let's say a, b, c. How to calculate the percentage share (or spatial share ha) of these individual (a,b,c) types of lots in the gap ? Ex: ID1 gap: 30% - type a 50% - type b 20% - type c Thank you.

  6. Yes, I want to add a point in existing Postgres table but via qgis (digitize it) by adding exact coordinates (XY) values. In ArcGIS, I can do that by using Absolute XY (F6). I know how to do it in qgis by using a plugin name LatLon Tools. The issues is those latlon tools cannot be used to add coordinate when when the data is called from the Postgres database.
  7. so you want to add another point in existing postgres database? or you want to load point from postgres database?
  8. Earlier
  9. Basically, I want to add a feature point by a coordinate in QGIS where the feature itself is loaded from Postgres database. I know there is a plugin called LatLon Tools which provides the tool but sadly it cannot be done when the layer is loaded from Postgres database. anyone knows how to do it?
  10. Emlid has debuted the Reach RS2, a fully-featured multi-band RTK receiver. All of its features are available out of the box, along with a survey app for iOS and Android. The Reach RS2 tracks L1/L2 bands on GPS, GLONASS and BeiDou, and L1/L5 on Galileo, and acquires a fixed solution in seconds. It achieves centimeter-level precision for surveying, mapping and navigation and maintains robust performance even in challenging conditions. Centimeter accuracy can be achieved on distances up to 60 km in RTK and 100 km in PPK mode. Up to 22 hours of autonomous work when logging data and up to
  11. Until recently, there have been no clear assessment of how much CO2 and the role that soils contribute in emissions relative to other greenhouse gases. Now a global scale map using statistical models and satellite imagery, along with other work by scientists, is beginning to indicate how much land use and soil change can affect our planet’s climate. In a recent study, a series of machine learning models using multiple nonlinear regression (MNLR), random forest regression (RFR), support vector regression (SVR), and artificial neural network (ANN) were assessed for determining Rs datasets
  12. The Artemis generation of lunar explorers will establish a sustained human presence on the Moon, prospecting for resources, making revolutionary discoveries and proving technologies key to future deep space exploration. To support these ambitions, NASA navigation engineers from the Space Communications and Navigation (SCaN) program are developing a navigation architecture that will provide accurate and robust position, navigation and timing (PNT) services for the Artemis missions. GNSS signals will be one component of that architecture. GNSS use in high-Earth orbit and in lunar space will
  13. Germany is the first United States ally to order the new military code (M-code)-capable Military GPS User Equipment (MGUE). The Space and Missile Systems Center’s Space Production Corps achieved the major milestone on Sept. 30, when GPS Foreign Military Sales (FMS) office received its first M-code MGUE order.Germany is expected to receive delivery of its first M-code receivers this year. SMC is facilitating international access and availability of M-code user equipment as directed by the Secretary of the Air Force and the Office of the Secretary of Defense to 58 authorized nations. A
  14. Jika Anda hanya ingin menyesuaikan nilai Z, Anda dapat menggunakan Global Mapper untuk melakukan ini. 1. Pertama muat data raster, lalu data GCP sebagai titik vektor. 2. Selanjutnya, ubah data raster menjadi fitur titik. 3. Kemudian gunakan 'LIDAR QC' untuk menyesuaikan fitur titik ke data GCP. 4. Setelah penyesuaian, ubah fitur titik kembali ke kisi ketinggian raster.

  16. The Sea of Galilee (also known as the Sea of Tiberias, Lake Tiberias, Lake of Gennesaret, and Lake Kinneret), located in northeast Israel, is the world’s lowest freshwater lake. After the Dead Sea, the Sea of Galilee is the world’s second-lowest lake in the world. The lake measures 21 kilometers (13 miles) north-south, and it is only 43 meters (141 feet) deep. Most of the inflow of water to the Sea of Galilee arrives via the Jordan River from the north, although some underground springs drain into the lake. Water levels have been dropping for the past two decades, reaching a nearly a
  17. According to the National Snow and Ice Data Center in the United States, about 69% of freshwater supplies are stored in Earth’s ice sheets and glaciers. This means measuring water content in ice and glaciers is critical to understanding future changes to water supplies as well as sea level rise, where melting glaciers and ice sheets are the biggest contributing factor in this rise. Modern satellites now allow us to make more accurate mass measurements to large areas covered by ice, which also allows us to better understand sea level change. Measuring mass for ice sheets and glaciers
  18. I am an avid user of the Mapbox JS library, and I use to map points of interest in some of our projects, like locations of survey targets for monitoring purposes. https://www.mapbox.com/mapbox-gljs THe latest branch now includes improved support for 3D terrain, but I am still nt seeing support for negative elevations- i.e underground. But with the news that Mapbox 2.0 is no longer open source, What are your thoughts about it? Certainly it has an imapct on the projects that depend on the underlying Mpabox libraries, but they said its not gonna affect 99% of the existing
  19. DJI — one of the largest and most popular drone companies in the world — has been added to the US Department of Commerce’s Entity List, designating the Chinese company as a national security concern and banning US-based companies from exporting technology to the company. DroneDJ first reported the news, which was confirmed by Reuters based on a conference call with a senior commerce official. The Department of Commerce referred questions to the Federal Register listing. DJI declined to comment. The ban was put in place through the same mechanism as the US government’s ongoing ban on
  20. There’s a new member of DJI’s Enterprise line of drones. It’s the Mavic 2 Enterprise Advanced, and it features a new 32X camera, a DJI-produced thermal sensor, and a Real-Time Kinematic module for centimeter-level accuracy. The new model comes a little more than two years after DJI released its Mavic 2 Enterprise, which proved a very popular drone with First Responders – ranging from lifeguards to law enforcement to Search and Rescue teams. It was that drone which heralded the modular design, allowing such extras as lights, a loudspeaker, and more to be affixed to the drone depending on t

  22. On November 21st, Sentinel-6 was launched by the European Space Agency (ESA) using a SpaceX Falcon 9 rocket. The satellite was developed in partnership with NASA and other agencies and was named after former NASA Earth Science Division Director Michael Freilich.[1] The recent launch of Sentinel-6 Michael Freilich/Jason CS is the latest mission that will collect sea level measurements at more frequent intervals to monitor the effects of climate change on our oceans. With one of the biggest threats of climate change being the rise of ocean levels, this represents an important tool for scie
  23. Mr. Lurker was kind enough to redirect me to this thread as I was going crazy over failing to post or finding spacial forum. So may I hereby request to please reactivate my account? I do intend to be more active from now on.
