MapLegendExtraction

This dataset contains high-resolution geological maps annotated with the bounding boxes of their embedded map legends, along with structured JSON representations of legend content. Designed for training models in legend detection, legend parsing, and map understanding.

We provide legend images for map data provided by the open platform. If you send the request URL to the server along with the authenticated key value, you can receive a legend in PNG / JPG / XML format. The OGC (Open Geospatial Consortium) standard API is an international standard developed for sharing and interoperability of spatial data, enabling efficient provision and use of various geographic information such as maps, features, and rasters on the web. The latest OGC API adopts a RESTful structure to enhance development convenience and expandability, and provides legend information used in WMS and WFS.

Soil Taxonomic Units in the map legend are named with the following convention: the four first letters abbreviate the taxon up to Subgroup level, a number differentiate among similar Subgroups, and the last two characters are linked to a lithostratigraphic unit. If defined, series are shown between brackets (Information source: Gómez-Miguel et al. 2015).

This dataset is obtained from MapBiomas.

Landsat mosaics are used to generate classifications that produce thematic maps of land cover and land use for each year. Within the framework proposed by MapBiomas Amazonía, these maps will be updated whenever improvements are made to the classification algorithm. This classification method is dynamic, with the aim of improving the classification of each typology.

Here you can access annual land cover and land use maps of the Amazon, organized by country, map scale (1:250,000), and year.

Important: When creating a single mosaic or calculating statistics on the maps, you must consider that:

To calculate area, the use of an appropriate metric projection is required.
All data is in GeoTIFF format and uses LZW compression. To obtain class reference codes, visit:
LEGEND CODES – COLLECTION 6.0 Annual maps are combined into a single file with multiple bands, where each band represents one year from the historical series (the first band corresponds to the first year of the series). The international boundaries used by MapBiomas Amazonía are those used by RAISG and may differ from files from other sources.

Use the Interactive Legend template to allow users to filter layers in your map by toggling the visibility of features based categories and ranges in the legend. Choose from paired feature-specific effects, such as bloom and blur, to distinguish between selected items in the legend and the remaining data. Choose from several options to emphasize selected items in the legend while other items remain on the map in muted colors. Examples: Form a better understanding of the spatial relationship between map features by changing the visibility of the content. Present economic data relevant to numerical range values of interest during a seminar. Analyze crime data to facilitate decision making of law enforcement distribution pertaining to specific crime categories.

In the overview of map layout neat lines are only in the neighboring countries territory of the map sheets which contain the Czech Republic territory.

EMAG2v3: Earth Magnetic Anomaly Grid at 2-arc-minute Resolution, Version 3NOAA's National Centers for Environmental Information (NCEI)EMAG2v3: the Earth Magnetic Anomaly Grid (2 arc-minute resolution), version 3 is compiled from satellite, ship, and airborne magnetic measurements. Magnetic anomalies result from geologic features enhancing or depressing the local magnetic field. These maps increase knowledge of subsurface structure and composition of the Earth's crust. Global magnetic anomaly grids are used for resource exploration, navigation where GPS is unavailable (submarine, directional drilling, etc.), and for studying the evolution of the lithosphere.The 2017 release of the EMAG2v3 utilizes updated precompiled grids and a revised process for accurately incorporating the long-wavelength anomalies, as modeled by the satellite-based MF7 lithospheric field model. It is an update from the previous EMAG2v3 released by NCEI in 2016. EMAG2v3 further differs from the previous EMAG2 (version 2), which relied on an ocean age model to interpolate anomalies into non-existent data areas and on the earlier MF6 model. EMAG2v3 relies solely on the data available. As a result, EMAG2v3 better represents the complexity of these anomalies in oceanic regions and accurately reflects areas where no data has been collected. The current version reports anomalies in two ways:A consistent altitude of 4 km (referred to as Upward Continued)Anomaly altitude at Sea LevelThe magnetic anomaly values in nanotesla (nT) are displayed using the color ramp below:Tips for using this web map:View the legend or toggle layers on/off with the buttons in the upper-right.Click on the map to see a popup reporting the data value at that location. Click on the arrow scroll through values for the Upward Continued (UpCont), Sea Level, and Error grids.The latitude/longitude of the mouse pointer is displayed in the lower-left.The EMAG2 dataset illustrates Earth evolution (plate tectonics and crustal interaction with the deep mantle). Distinct patterns and magnetic signatures are attributed to the formation (seafloor spreading) and destruction (subduction zones) of oceanic crust, and the formation of continental crust by accretion of various terranes to cratonic areas and large scale volcanism (both on continents and oceans).Magnetization is weaker at the equator and stronger at high latitudes, reflecting the strength of the ambient geomagnetic field, which induces magnetization in rocksStripes of alternating magnetization in the oceans are due to sea floor spreading and the alternating polarity of the geomagnetic fieldVery old crust (North American Shield, Baltic Shield, Siberian Craton) have strongest magnetization, seen as dark shades of blueThere are four related ArcGIS services providing access to EMAG2v3:Color shaded relief image (tiled, Web Mercator projection)Color shaded relief image (tiled, WGS84 geographic)Multi-layer map serviceImage service (data values)

Mapped polygons at 1:7.5 million scale contain many vegetation types. The map portrays the zonal vegetation within each mapped polygon. Zonal sites are areas where the vegetation develops under the prevailing climate, uninfluenced by extremes of soil moisture, snow, soil chemistry, or disturbance, and are generally flat or gently sloping, moderately drained sites, with fine-grained soils (Vysotsky 1927). Large areas of azonal vegetation that are dependent on specific soil or hydrological conditions, such as mountain ranges and large wetlands, were also mapped. The legend contains five broad physiognomic categories: B — barrens, G — graminoid-dominated tundras, P — prostrate-shrub-dominated tundras, S — erect-shrub-dominated tundras, and W — wetlands. These are subdivided into 15 vegetation mapping units with numeric codes added to the alphabetic codes. The mapping units are named according to dominant plant functional types except in the mountains where complexes of vegetation are named according to the dominant bedrock (carbonate and noncarbonate mountain complexes). The coloring scheme of the map is suggestive of the physiognomy of the vegetation. The plant functional types are based on a variety of criteria including growth form (e.g., graminoids, shrubs), size (e.g., dwarf and low shrubs), and taxonomical status (e.g., sedges, rushes, grasses). The legend takes into special consideration the stature of woody shrubs, which is a major diagnostic feature of zonal vegetation in the Arctic (Edlund and Alt 1989, Walker et al. 2002, Yurtsev 1994). Very steep bioclimate gradients occur in mountains, so these areas are mapped as complexes of elevation belts. Mountainous areas of the map are shown with hachures; the background color indicates the nature of the bedrock, and the color of the hachures indicate the bioclimate subzone at the base of the mountains.

The scientifically based soil mapping (soil inventory) with the publication of soil maps is the most important basis for soil use, soil protection and soil research. These are surface data of soil-based mapping for the distribution and characteristics of the soils. They are the basis for the ground map 1: 50 000. The Ground Map of North Rhine-Westphalia 1: 50 000 (BK 50) represent the distribution of soils grouped into soil units in the leafy area. The map legend contains for each floor unit information on the soil type stratification up to 2 m depth, the soil types and the geological base rock. A special column shows the values of soil estimation, suitability for use, yieldability and workability, as well as the water conditions of the soils. The soil maps form an important basis for tasks in agriculture, forestry, land planning, land maintenance, water management and nature conservation, as well as for research, teaching and teaching. The soil maps of the Wiedenbrück district as well as the district and the city of Iserlohn reproduce the soil-related conditions across leaf boundaries. Each of them includes an explanatory book with a list of fonts and maps, in which, after an introduction, the factors of soil formation, the soil units, the land use, the usable rocks and ores, the building ground and the groundwater are discussed. There are: Ground map of the Wiedenbrück circle 1: 50 000. 19972 (with explanation) Ground map of the district and city of Iserlohn 1: 50 000. 1972 (with explanation)
