    Convert CRS from ESRI:102673 to EPSG:4326

    Zach
    By Zach,
    Hi readers, I have a dataset of ~60,000,000 rows of lidar point data. All spatial reference points are projected using ESRI:102673 (full WKT here: https://epsg.io/102673). I need to convert this to latitude and longitude, EPSG:4326, so that I can overlay other layers and have them match up in the same spacial reference. I am using Python, so any transformation I can do using numpy or pandas will work, or any other free software that gets the job done would be great. This tool (https://

    Field calculation ?

    By adamekcerv,
    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

    Add Feature Point by Coordinate (Long,Lat) in QGIS From Postgis Layer

    Reyalino
    By Reyalino,
    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?

    Emlid launches Reach RS2 multi-band RTK receiver

    Lurker
    By Lurker,
    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 

    Mapping Carbon Dioxide Emissions from Soil Respiration

    Lurker
    By Lurker,
    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 ve

    • Hi too, In AutoCAD Civil3D, you can create new surface of road according to your requirement and export it as elevation model. Add it with existing surface in Global Mapper and merge all surfaces.
    • If your work requires any sort of graphical visualization of data, chances are you’ve run into Tableau. If you’ve been using Tableau but want to learn how to really harness its full power for data science, join expert Matt Francis in this course as he shows you how to take your skills to the next level. Matt starts with one of the most important features in Tableau: the difference between the green and blue pills (discrete and continuous data) and how this affects every single action Tableau performs. He then shows how to connect to and combine data from different data sources, how to create different charts to make sense of data, ways to transform your data with calculations, and how to create interactive maps. Finally, Matt details ways to present data effectively and how to make engaging dashboards. Whether you want to learn more about Tableau as a whole, or if you just want to improve your knowledge of a single subject, this course will help up your Tableau game. download: https://paste2.org/GPgveBJM

    • Without mathematics no science would survive. This especially applies to the engineering sciences which highly depend on the applications of mathematics and mathematical tools such as optimization techniques, finite element methods, differential equations, fluid dynamics, mathematical modelling, and simulation. Neither optimization in engineering, nor the performance of safety-critical system and system security; nor high assurance software architecture and design would be possible without the development of mathematical applications. De Gruyter Series on the Applications of Mathematics in Engineering and Information Sciences (AMEIS) focusses on the latest applications of engineering and information technology that are possible only with the use of mathematical methods. By identifying the gaps in knowledge of engineering applications the AMEIS series fosters the international interchange between the sciences and keeps the reader informed about the latest developments.
