LA PHOTOGRAMMETRIE APPLIQUE A LA CONNAISSANCE DES
PROPRIETAIRES DES TERRES SOMMAIRE
la Compania Mexicana Aecrofoto, S. A., a réalisé des études aérophotographiques sur de
grandes étendues de terrain au Mexique afin de localiser les régions qui, moyennantdes
procédés juridiques officiels, seront soumis au contróle du Gouvernement mexicain dans le
but de satisfaire les besoins agraires du pays (Autorisé par le Département des Affaires
Aaraires).
La réalisation de ces travaux a été difficile à cause de l'importante superficie du territoire
en queslion, du climat et des moyens de communication. Cependant, deux ans aprés le
commencement des travaux, la Compañia avait déjà utilisé le matériel photographique de
ses archives pour 425,700 km” et photographié Une superficie de 439,300 km°. Cette étude
a permis de savoir à qui appartiennent les terres et d'arriver ainsi à une plus profonde
connaissance du pays.
PHOTOGRAMMETRY APPLIED TO LAND OWNERSHIP ABSTRACT
The Companía Mexicana Aerofoto, S. A., has been surveying large tracts of land in the
Mexican Republic by means of aerial photography in order to locate those areas which
through legal processes will come under the control of the Goverment with a view to sa-
tisfying its agrarian needs. (Authorized by the Departament of Agrarian Affairs).
The execution of this project. was difficult because of problems revolving about the im-
mense expanse of land involved, climatic conditions, and communications. In the two years
since the initiation of the project the Companía has used 425,700 square kilometers of pho-
tographic material from its files and has surveyed a total of 439,300 square kilometers.
This survey has determined the location of landed property and has led to an increased
knowledge of the country.
ANWENDUNG DER PHOTOCRAMMETRIE FÜR LANDBESITZ ZUSAMMENFASSUNG
Die Compania Mexicana Aerofoto hct grosse Gebiete in der mexikanischen Republik gemes-
sen, um jene Flächen zu lokalisieren, die in Zukunft durch gesetzliche Vermittlung unter
der Kontrolle der Nation stehen werden, um ihre agrarische Notwendigkeiten zu befriedi-
gen (Autorisiert vom Ministerium des Ackerbaues).
Die Durchführung dieser Arbetit war schwierig, da die Bedingungen, verursacht durch die
grosse Ausdehnung des Gebietes, des Klimas und der Strassen nicht immer günsting waren.
In den zwei Jahren seitdem die Arbeiten angefangen haben, hat die Firma von ihrem
Archive 425,700 km” photographisches Material veróffnet. Ausserdem beflog und vermass
sie 439,300 km” mehr, welches viel dazu beitrug um den Grundbesitz festzustellen und
gleichzeitig bessere Kenntnis des Landes selbst zu erhalten.
