{"type":"Collection","id":"mro_ctx_controlled_usgs_dtms","stac_version":"1.0.0","description":"These data are Ames Stereo Pipeline generate MRO CTX DTMs. Data are generated from relatively controlled CTX data and are then absolutely controlled to MOLA using the ASP `pc_align` application. Therefore, these data are absolutely controlled to MOLA. Data are projected to the appropriate IAU Well-known Text v2 (WKT2) represented projection. For documentation and to discuss these data see [our documentation pages](https://stac.astrogeology.usgs.gov/docs/data/mars/ctxdtms/).\nNote: Some DTMs in this collection are jittery and/or contain large regions of missing data. These DTMs are not an improvement over lower-resolution datasets like MOLA. Those DTMs are being released for the sake of completeness. If a DTM user processes a poor DTM to a higher quality product, please let us know.","links":[{"rel":"self","type":"application/json","href":"https://g6goyz4w56.execute-api.us-west-2.amazonaws.com/prod/collections/mro_ctx_controlled_usgs_dtms"},{"rel":"cite-as","href":"https://doi.org/10.5066/P9JKVWR3"},{"rel":"service-doc","href":"https://stac.astrogeology.usgs.gov/docs/data/mars/ctxdtms/","type":"text/html; charset=UTF-8","title":"Data Documentation"},{"rel":"service-doc","href":"https://registry.opendata.aws/nasa-usgs-controlled-mro-ctx-dtms/","type":"text/html; charset=UTF-8","title":"AWS Open Data Registry Metadata Entry"},{"rel":"parent","type":"application/json","href":"https://g6goyz4w56.execute-api.us-west-2.amazonaws.com/prod"},{"rel":"root","type":"application/json","href":"https://g6goyz4w56.execute-api.us-west-2.amazonaws.com/prod"},{"rel":"items","type":"application/geo+json","href":"https://g6goyz4w56.execute-api.us-west-2.amazonaws.com/prod/collections/mro_ctx_controlled_usgs_dtms/items"},{"rel":"http://www.opengis.net/def/rel/ogc/1.0/queryables","type":"application/schema+json","href":"https://g6goyz4w56.execute-api.us-west-2.amazonaws.com/prod/collections/mro_ctx_controlled_usgs_dtms/queryables"},{"rel":"aggregate","type":"application/json","href":"https://g6goyz4w56.execute-api.us-west-2.amazonaws.com/prod/collections/mro_ctx_controlled_usgs_dtms/aggregate","method":"GET"},{"rel":"aggregations","type":"application/json","href":"https://g6goyz4w56.execute-api.us-west-2.amazonaws.com/prod/collections/mro_ctx_controlled_usgs_dtms/aggregations"}],"stac_extensions":["https://stac-extensions.github.io/projection/v1.0.0/schema.json","https://stac-extensions.github.io/datacube/v1.0.0/schema.json","https://raw.githubusercontent.com/thareUSGS/ssys/main/json-schema/schema.json","https://stac-extensions.github.io/scientific/v1.0.0/schema.json"],"title":"Mars Reconnaissance Orbiter (MRO) Context Camera (CTX) Digital Terrain Models (DTMs)","sci:doi":"10.5066/P9JKVWR3","sci:citation":"Laura, J.R., Adoram-Kershner, L.A., Meyer, D.P., Wheeler, B.H., Bauck, K.H. and Fergason, R.L., 2023.
