Forwarding a request for assistance from the PROJ mailing list -- this is a great opportunity for our Spanish, Catalan, Austrian, Slovakian and Brazilian communities to contribute (amongst others!)
---------- Forwarded message --------- From: Even Rouault <[email protected]> Date: Mon, 2 Dec 2019 at 09:18 Subject: [PROJ] Interested in helping for inclusion of grids for Spain, Austria, Slovakia, Brazil ? To: <[email protected]> Hi, I'm requesting help from good wills of the community to help us grow our datasets of grids at https://github.com/OSGeo/proj-datumgrid/ Below a few candidates I've identified, mentionned in EPSG and with a number of them with download links, but license clarification would be needed. Community members from those countries are probably in a better position than me to connect with the relevant authority and see if they'd be willing to adopt one of the licenses mentionned at https://github.com/OSGeo/proj-datumgrid#about-the-datum-grid-package Spain ----- * Peninsula and Baleares: Anyone from the Spanish community to help clarifying license of https://www.fomento.gob.es/recursos_mfom/gridshift1.zip (ED50 to ETRS89), presumably whith IGN Spain The download link is accessible from https://www.fomento.gob.es/organos-colegiados/consejo-superior-geografico/csg/etrs89/etrs89-nuevo-sistema-de-referencia-geodesico-oficial-en-espana This file has a sort of CC license (https://gist.github.com/rouault/1ff4ad2d8053e068f9dbf451572692f4) but with a annoying non-modification clause that makes it incompatible with our requirements (we might want to transform it to another format like GeoTIFF), and no version/link to the actual CC license. * Catalonia: Grid specific to Catalonia for ED50 to ETRS89 : 100800401.gsb File found in http://www.icgc.cat/content/download/48766/337962/version/1/file/Malla_NTv2_11_03.zip but no explicit license mention. https://www.icgc.cat/en/Web/Help/Legal-notice has a vague mention of Creative Commons, but no precise identification of which variant of it, and which version. Austria ------- The AT_GIS_GRID.gsb grid for MGI to ETRS89 is available at http://www.bev.gv.at/portal/page?_pageid=713,2157075&_dad=portal&_schema=PORTAL : http://www.bev.gv.at/pls/portal/docs/PAGE/BEV_PORTAL_CONTENT_ALLGEMEIN/0200_PRODUKTE/UNENTGELTLICHE_PRODUKTE_DES_BEV/GIS-Grid.zip Copyright info I could find is "Hinsichtlich seiner Datenbanken verfügt das BEV über das ausschließliche Werknutzungsrecht gemäß §§ 40f bis 40h UrhG und das sui generis-Recht gemäß §§ 76c bis 76e UrhG." which by itself is not super promising. Slovakia -------- https://www.geoportal.sk/en/geodeticke-zaklady/download/ offers for download 3 grids referenced by EPSG: Slovakia_ETRS89h_to_Baltic1957.gtx Slovakia_ETRS89h_to_EVRF2007.gtx Slovakia_JTSK03_to_JTSK.LAS / .LOS I've emailed the contact mentionned on the site to get info regarding the license. But wouldn't hurt to get feedback of knowledgeable people too. Brazil ------ Looking for official download links & license for the following: Corrego Alegre 1961 to SIRGAS 2000: CA61_003.gsb Corrego Alegre 1970-72 to SIRGAS 2000: CA7072_003.gsb SAD69 to SIRGAS 2000: SAD69_003.gsb SAD69(96) to SIRGAS 2000: SAD96_003.gsb https://www.killetsoft.de/p_gdln_e.htm has download links but official ones from IBGE would be preferable if possible. Of course there are certainly gaps to fill for other countries I've not mentionned...
