More 30m-resolution DEM elevation data has been installed on GPS Visualizer's server: new LIDAR-based files ("ODP1") for Iceland, and NASA SRTM1 data for Central America, the Caribbean, and northern Queensland. When tickmarks are added to a Google or Leaflet map, the "description" field of the tickmark will now contain the distance (for time-based tickmarks) or time (for normal distance tickmarks), if your input file contains the relevant data. If you create a Google or Leaflet map where the markers are displayed in folders in the marker list, you can use the gv_options.marker_list_options.folder_zoom parameter to automatically include a "zoom to contents" link next to the name of the folder. The JavaScript-based tool that can retrieve elevation data from the Google Maps Elevation API (using your Google API Key) has been updated so that it can look up 500 points at once this saves both time and calls to the API. GPS Visualizer's "NED1" collection of elevation data has been updated with the latest files from the US Geological Survey's 3D Elevation Program, which uses LIDAR to improve the accuracy of elevation data. GPS Visualizer now has basic support for Points, LineStrings, MultiLineStrings, Polygons, and MultiPolygons in GeoJSON (.json) FeatureCollection files. New 30m-resolution digital elevation files from Europe - compiled by "Sonny" - have been installed on GPS Visualizer's server. Please send a message if you encounter any new bugs. For the first time since 2017, GPS Visualizer's hardware has been upgraded. (The lower-resolution SRTM3 data is now only used in Siberia & Greenland.) Furthermore, the SRTM1 data has been upgraded to the NASA DEM, which uses SRTM1 as a base but re-processes it and enhances it for better accuracy. Now that GPS Visualizer has a lot more disk space to work with, 1-arc-second digital elevation model (DEM) data has been installed for the entire world. This starts each track's elevation at "zero" and shows the relative change rather than the absolute altitude. When making profiles, you can now specify "Net Elevation" as the y-axis. GPS Visualizer is based in Portland, Oregon, and has been on the Web since October 2002. xlsx),Īnd of course tab-delimited or comma-separated text. Garmin MapSource/ BaseCamp/ HomePort (.gdb), GPX (a standard format used with many devices and programs, including Garmin's eTrex, GPSMAP, Oregon, Dakota, Colorado, & Nüvi series), GPS Visualizer can read data files from many different sources, including but not limited to: Or, you could send an Amazon wish list item. Its broad compatibility with common software, including spreadsheet and database programs, maintains its popularity for straightforward data operations.GPS Visualizer is a free service and hopefully always will be however, if you find it interesting, time-saving, or just plain fun, you can say "thanks" - and encourage further development - by clicking the button above and making a contribution via credit card or PayPal. Special handling is needed for fields containing delimiters, usually by enclosing them in quotes and escaping internal quotation marks.ĭue to its simplicity and flexibility, CSV is favored for basic data exchange and import/export tasks across different programs, despite not being suitable for complex or relational data structures. The structure consists of delimited rows and fields without a standard schema, treating all data as strings, with interpretation dependent on the importing application.ĬSV files may include optional headers and support various text encodings like UTF-8 and ASCII. As a plain text format, it's universally compatible and easy to edit. □ The `.csv` (Comma-Separated Values) format is a simple text format for tabular data, with each line representing a table row and fields separated by a delimiter, typically a comma, though alternatives like semicolons or tabs are also used. It's commonly used for exchanging data between different programs and for exporting and importing large amounts of data due to its simplicity and wide compatibility. This format is widely supported by many applications, including spreadsheet and database software. Each line in the file corresponds to a row in the table, and columns in a row are separated by commas. csv (Comma-Separated Values) format is a plain text format used for representing tabular data.
