At this scale 1cm on the map represents 1km on the ground. Each map covers a minimum area of 0.5 degrees longitude by 0.5 degrees latitude or about 54 kilometres by 54 kilometres. The contour interval is 20 metres. Many maps are supplemented by hill shading.

This is a georeferenced raster image of a printed paper map of the Oasis Lake, Manitoba / Ontario region (Sheet No. 053E08), published in 1973. It is the first edition in a series of maps, which show both natural and man-made features such as relief, spot heights, administrative boundaries, secondary and side roads, railways, trails, wooded areas, waterways including lakes, rivers, streams and rapids, bridges, buildings, mills, power lines, terrain, and land formations. This map was published in 1973. Maps were produced by Natural Resources Canada (NRCan) and it's preceding agencies, in partnership with other government agencies. Please note: image / survey capture dates can span several years, and some details may have been updated later than others. Please consult individual map sheets for detailed production information, which can be found in the bottom left hand corner. Original maps were digitally scanned by McGill Libraries in partnership with Canadiana.org, and georeferencing for the maps was provided by the University of Toronto Libraries and Eastview Corporation.

Title: Kaouar Oasis, World Aeronautical Chart - Scale: 1000000 - Sheet number/Numéro de feuille/Bladnummer: 663

Being the national mapping agency of India, Survey of India has the mandate to provide the map on Antarctica region. Since 10th Expedition to Antarctica (1991-92), Survey of India has been taking part actively in scientific activity/map mapping of unique terrain. During the first few expeditions the horizontal and vertical control was provided to establish the datum for future mapping needs. In the successive expeditions, mapping on scale 1:5,000 with contour interval 5 m and scale 1:1,000 with contour interval 1 m has been taken up.

High-resolution Oasis maps are imperative for obtaining ecological and socio-economic development of arid regions. However, due to the late establishment and relatively niche nature of the oasis discipline system, there are no high-precision datasets related to oases in the world to date. To fill this gap, we conducted detailed visual interpretation of remote sensing images on Google Earth Professional or Sentinel II in summer 2020, and constructed for the first time a high-precision dataset of China's oases (abbreviation HDCO) with a resolution of 1 meter, covering 1,465 oases with an area larger than 0.01 km2. These oases collectively cover an expansive area of 275143.30 km², equivalent to approximately 8.12% of China's dryland area. The kappa coefficient for this dataset validated by the field survey was 0.8686 and the AUC value for the ROC curve was 0.935. The accuracy obtained from the validation using a random hexagonal grid is 95.73%. In addition, we added information on the geographic coordinates, climatic conditions, major landforms, and hydrological features of each oasis to the attribute table of the dataset. This dataset enables researches to quantitatively monitor location, area, and dynamic changes of oases, fosters explore the relationship between oases and human under climate change and urbanization.

Title: Siwa Oasis, Western Desert Province - Scale: 25000 - Sheet number/Numéro de feuille/Bladnummer: 2

The dataset contains vegetation type in the middle reaches of the Heihe River Basin, which was used to validate products from remote sensing. It was generated from investigating the land cover strips of CASI during 2012. Instruments: High-precision handheld GPS (2-3 m) and digital camera were used as main tools in the survey. Measurement method: Hierarchical classification is applied based on CASI data. According to various land types, pixel classifications is used for forest, grassland, bare land and building lands; in-situ observations and investigations are used for different crops.

Dataset contains: land types, including maize, leek, poplar trees, cauliflower, bell pepper, potatoes, endive sprout, orchard, watermelon, kidney bean, pear orchard, shadow, and non-vegetation, except for 14 others which are not classified. Observation site: core experimental areas with 5*5 matrix structure in the middle reaches of the Heihe river basin Date: From 25 June in 2012 (UTC+8) on.

Artificial Oases map of Amu river Basin includes four periods: 1990, 2000, 2010 and 2015. The data produced by the key laboratory of remote sensing and GIS, Xinjiang institute of ecology and geography, Chinese Academy of Sciences, the spatial resolution of data is 30 m. Data production Supported by the Strategic Priority Research Program of Chinese Academy of Sciences, Grant No. XDA20030101. The map of artificial oasis pattern in Amu river basin is based on Landsat TM and ETM image data in 1990, 2000, 2010 and 2015. Firstly, with the help of eCognition software, the object-oriented classification is carried out. Secondly, the classification results are checked and corrected manually. Finally, the data validation methods are field validation and high-precision image validation.

This digital geospatial data set is a compilation of reference points representing wells deeper than 300 meters in Nevada that were used for the regional ground-water potential map by Bedinger and Harrill (2004). The regional ground-water-potential map was developed to assess potential interbasin flow in the Death Valley regional ground-water flow system (DVRFS), a 100,000 square-kilometer region of southern Nevada and California. To obtain an adequate network of control points, Bedinger and Harrill (2004) used regional potential altitudes derived from surface-water features, ground-water levels, topographic settings and springs in addition to the deep well data. A set of general guidelines was developed to relate regional ground-water potential to these more readily observed surface and near-surface ground-water levels and to hydrologic characteristics of ground-water basins in the DVRFS (see "Larger Work Citation", Appendix 1).

Title: Sebha Oasis, World Aeronautical Chart - Scale: 1000000 - Sheet number/Numéro de feuille/Bladnummer: 541

After providing the Geodetic and Geophysical control in the Schirmucher Oasis, Survey of India has started large scale mapping in the Antarctica. The paper describes how the precise ground control network was formed which is a prerequisite for the desired large scale surveys, and the various steps involved in the detail and contour (i.e. original plane tabling) survey on 1:1,000 scale with 1 m contour interval for an area of 400 m ? 500 m located NW of Maitri. This mapping was specially done for extension of our permanent station in the Antarctica. Digital map of this area was made successfully after this fieldwork and given to concerned authorities.

In July 19, 2012 (UTC+8), the airborne LIDAR data is acquired in the foci area in the Heihe,middle reaches, which can provide high spatial resolution (m) and high precision (20 cm) of the surface elevation information. Based on airborne LIDAR data processing, the land surface DEM, DSM and point cloud density map were generated. By subtracting DSM and DEM directly, a Vegetation height product in the middle reaches of the Heihe River Basin was obtained. The product overall accuracy is 88%.

The data include a 1:10,000 scale map of the surfical glacial and periglacial features of the Amery Oasis, East Antarctica. Features currently include:

areas covered by exposed bedrock, fluvial sediments and moraine moraine ridges streams (flowing during the 2003/04 season) watercourses lakes cosmogenic exposure ages degree of weathering

and includes areas of glaciers, glacial bedforms, scree and patterned ground.

Rock samples are currently held by Duanne White (as at 2015-09-23), but will eventually be archived at Geoscience Australia.
