This work is part of the new structure planned for the Argentine Mining  System, mainly on fitting all the mines to a single geodetic system, in  order to attract new investments, national and foreign. ESTEIO  performed the following works:<\/p>\n<ol class=\"breadcrumb\" style=\"width: 790px;\">\n<li class=\"active\">\n<ul>\n<li> Creation of a high accuracy Geodetic Network with 688 points  distributed over the provinces of San Juan, La Rioja , Catamarca and  Salta.<\/li>\n<li> Location of 2,279 mines at Andes zone between the provinces of San Juan and Salta (north to northwest of Argentina).<\/li>\n<li> Establishment of 143 geodetic points for satellite images reference distributed over the mentioned provinces.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<p class=\"subtitulo\">Technical Features of the Project:<\/p>\n<p class=\"subtitulo1\">GPS Geodetic Network<\/p>\n<p>The  basic planning was a Geodetic Points Network connected to the National  Geodetic Network (POSGAR 94) for the establishment of 60 points  distributed over the 4 provinces.<\/p>\n<p>The medium error per vector among the points must not be superior to  0.05 m + D x 10-6 (D=distance in meters). This accuracy was reached  obeying the following procedures:<\/p>\n<ol class=\"breadcrumb\">\n<li class=\"active\">\n<ul>\n<li>Multi-session\/multi-station surveys; <\/li>\n<li>Minimum measuring time of 10 hours; <\/li>\n<li>Use of post-processing software (multi-session\/multi-station GEONAP).<\/li>\n<li>The final processing were performed by geodetic team of Universidad de la Plata, through an agreement with ESTEIO. The  Secondary Geodetic Network was created connected to these points and  obeyed similar measuring and post-processing concepts.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<p>***  POSGAR Geodetic Network is a 127 ground points network that covers all  the country, which coordinates are referred to WGS-84 ellipsoid.<\/p>\n<p class=\"subtitulo\">Location of Mines<\/p>\n<p>The  great number of topographic surveys performed, added to the huge  difficulty of access is an important differential to this project. For  the location of the mines were used many materials such as: existent  plans, GPS navigator receivers and topographic plans. The aid of  experienced trackers of each land was very important because many of  the mines were dated of early 1900&acute;s.<\/p>\n<p class=\"subtitulo\">Transportation and Resources<\/p>\n<p>Several  vehicles were used in this unique project, such as helicopters, 4WD  trucks, 4W motorcycles for salt mines and mountains, besides the  traditional and effective animal transportation.<\/p>\n<p>Other  resources were also important for the success of this project, among  them we mention satellite phones, BLU radios, GPS navigation receivers,  altimeters and laptops.<\/p>","protected":false},"excerpt":{"rendered":"<p>[IMAGEM_CAROUSEL] In 1997, ESTEIO performed one of the greatest Geodetic Network and Mines Location Works ever performed by a private company in Argentina called Subred Geodesica Minera y Reposicion de &#8230;<\/p>\n","protected":false},"author":1,"featured_media":6901,"parent":2207,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"template-left-sidebar.php","meta":{"footnotes":""},"class_list":["post-2214","page","type-page","status-publish","has-post-thumbnail","hentry"],"_links":{"self":[{"href":"https:\/\/www.esteio.com.br\/en\/wp-json\/wp\/v2\/pages\/2214","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.esteio.com.br\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.esteio.com.br\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.esteio.com.br\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.esteio.com.br\/en\/wp-json\/wp\/v2\/comments?post=2214"}],"version-history":[{"count":7,"href":"https:\/\/www.esteio.com.br\/en\/wp-json\/wp\/v2\/pages\/2214\/revisions"}],"predecessor-version":[{"id":6902,"href":"https:\/\/www.esteio.com.br\/en\/wp-json\/wp\/v2\/pages\/2214\/revisions\/6902"}],"up":[{"embeddable":true,"href":"https:\/\/www.esteio.com.br\/en\/wp-json\/wp\/v2\/pages\/2207"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.esteio.com.br\/en\/wp-json\/wp\/v2\/media\/6901"}],"wp:attachment":[{"href":"https:\/\/www.esteio.com.br\/en\/wp-json\/wp\/v2\/media?parent=2214"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
