    Sad day for ArcIMS

    Lurker
    By Lurker,
    related to my prev post here : http://gisarea.com/gis-discussion/what-are-the-deprecation-plans-for-arcgis-9-3-1-and-arcgis-9-4/ ESRI announce change of the deprecation plan, that can be see here : [hide] http://downloads2.esri.com/support/TechArticles/ArcGIS10and101Deprecation_Plan.pdf [/hide] Here is the updated text from the deprecation document: ArcGIS 10.0 ArcIMS lifecycle can be see here ; [hide] http://downloads2.esri.com/support/product%20life%20cycle/server_gis/ArcIMS

    Hide features

    maunaloa
    By maunaloa,
    Olla members :cool:! A made a great geodatabase, full with shapefiles. A wanted to select one feature from a shapefile, and hide the others on the same shapefile. Anyone have idea? I tested the f1>help>search for keyword, but i don't see any solution. Help meh:) Ahoy

    polyline editing in arcgis10

    maunaloa
    By maunaloa,
    Hi everyone! I have a small problem:) :shocked: In  arcgis 9.x i could do it that: i made a polyline, and if i wanted to continue draw that line, i double-clicked on it, and clicked on editor toolbars pen icon, and then i moved the mouse over the drawing area, and i could draw the line from end, or if clicked on the line with right mouse, and selected "flip", then i could draw from the other "end". In arcgis 10, if i want to continue an older line, this trick can't work :evil:. But flip o

    Question about Maplex labeling in ArcMap

    akbarchinaman
    By akbarchinaman,
    Sorry, not sure where to put this... I have a bunch of road lines, and I want to label every feature but not have any duplicates. However, if I turn on "never remove", the previously unplaced labels would not follow the placement rules, which I have set to Street placement, offset and curved. How do I force all labels, previously unplaced or not, to follow my placement rules?

    • Hi everyone This straightforward tool generates a stream order network from elevation data (DEM). The only input required is a DEM. As an open-source tool, it is accessible and easy to use. If you encounter any issues, feel free to contact me at [email protected].  Tested with ArcGIS Desktop 10.8.1😊 Let me know if you'd like further refinements Download Link   To create a stream network and determine its order in ArcGIS starting with a Digital Elevation Model (DEM), follow these general steps: Step 1: Prepare the DEM Load your DEM into ArcGIS. Ensure the DEM is hydrologically correct, without any errors like sinks or pits. Use the Fill tool from the Spatial Analyst toolbox to fill these voids Step 2: Flow Direction Use the Flow Direction tool to compute the direction of water flow across the DEM surface. This creates a raster that assigns a flow direction to each cell Step 3: Flow Accumulation Apply the Flow Accumulation tool to calculate the amount of flow accumulated for each cell based on the flow direction raster Step 4: Stream Threshold Set a threshold value for the Flow Accumulation raster to define streams. The Con (conditional) tool can be used to extract cells that meet this threshold. This step essentially defines what qualifies as a stream Step 5: Stream Link Use the Stream Link tool to assign unique identifiers to connected stream segments. Step 6: Stream Order Apply the Stream Order tool to calculate the hierarchical order of streams (e.g., Strahler or Shreve order). Step 7: Vectorization (Optional) Convert the raster stream network to a vector format using the Stream to Feature tool. This makes the streams easier to visualize and analyze. With these steps, you'll have a stream network derived from your DEM with ordered streams that can be used for further hydrological analysis.
    • i just check with website downtime checker, and the sites has been down for couple days, just wait till its up,   
    • Does anyone know whats going on with Lavteam? I have not been able to access the site for two days now.
    • NASA and the Italian Space Agency made history on March 3 when the Lunar GNSS Receiver Experiment (LuGRE) became the first technology demonstration to acquire and track Earth-based navigation signals on the Moon’s surface.   The LuGRE payload’s success in lunar orbit and on the surface indicates that signals from the GNSS (Global Navigation Satellite System) can be received and tracked at the Moon. These results mean NASA’s Artemis missions, or other exploration missions, could benefit from these signals to accurately and autonomously determine their position, velocity, and time. This represents a steppingstone to advanced navigation systems and services for the Moon and Mars.   “On Earth we can use GNSS signals to navigate in everything from smartphones to airplanes,” said Kevin Coggins, deputy associate administrator for NASA’s SCaN (Space Communications and Navigation) Program. “Now, LuGRE shows us that we can successfully acquire and track GNSS signals at the Moon. This is a very exciting discovery for lunar navigation, and we hope to leverage this capability for future missions.”   The road to the historic milestone began on March 2 when the Firefly Aerospace’s Blue Ghost lunar lander touched down on the Moon and delivered LuGRE, one of 10 NASA payloads intended to advance lunar science. Soon after landing, LuGRE payload operators at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, began conducting their first science operation on the lunar surface. With the receiver data flowing in, anticipation mounted. Could a Moon-based mission acquire and track signals from two GNSS constellations, GPS and Galileo, and use those signals for navigation on the lunar surface?    Then, at 2 a.m. EST on March 3, it was official: LuGRE acquired and tracked signals on the lunar surface for the first time ever and achieved a navigation fix — approximately 225,000 miles away from Earth.   Now that Blue Ghost is on the Moon, the mission will operate for 14 days providing NASA and the Italian Space Agency the opportunity to collect data in a near-continuous mode, leading to additional GNSS milestones. In addition to this record-setting achievement, LuGRE is the first Italian Space Agency developed hardware on the Moon, a milestone for the organization.   The LuGRE payload also broke GNSS records on its journey to the Moon. On Jan. 21, LuGRE surpassed the highest altitude GNSS signal acquisition ever recorded at 209,900 miles from Earth, a record formerly held by NASA’s Magnetospheric Multiscale Mission. Its altitude record continued to climb as LuGRE reached lunar orbit on Feb. 20 — 243,000 miles from Earth. This means that missions in cislunar space, the area of space between Earth and the Moon, could also rely on GNSS signals for navigation fixes.   source: NASA
