MAP GENERALIZATION [6 records]

Record 1 2009-03-09

English

Subject field(s)
  • Ecology (General)
  • Environmental Studies and Analyses
  • Technical Surveys
CONT

In a generic sense, the application of ecological land surveys(ELS) to environmental impact assessment... can be considered as a form of ecological characterization. ELS involves the delineation and description of units of land based on the integration of information on geomorphology, soils, vegetation, climate, water and fauna. Land units may be interpreted at any one of six hierarchical levels of generalization and presented in map form using scales ranging from 1 : 1, 000, 000 down to 1 : 2, 500.

French

Domaine(s)
  • Écologie (Généralités)
  • Études et analyses environnementales
  • Levés et relevés techniques (Arpentage)
OBS

"Relevé" : Ensemble des opérations destinées à recueillir des données sur le terrain. Note : Le but d'un relevé varie selon le domaine d'intérêt. Pour une étude d'impact, il s'agit principalement de faire l'inventaire du milieu. En génie, il s'agit de recueillir les mesures nécessaires pour réaliser une carte, un plan. On devrait d'ailleurs employer le terme "levé" dans ce sens.

Spanish

Campo(s) temático(s)
  • Ecología (Generalidades)
  • Estudios y análisis del medio ambiente
  • Levantamientos técnicos
CONT

La geomorfología es de importancia fundamental para todos los inventarios ecológicos del territorio, tanto por su valor esencial para la ecología como para su correlación con otros atributos de la tierra (clima, suelos, agua, vegetación y uso).

Record 2 2007-01-31

English

Subject field(s)
  • Radar, Radio Guidance and Goniometry
  • Spacecraft
  • Remote Sensing
DEF

The process of eliminating locational and content discrepancies in the representation of features at the edges of adjacent map sheets or tiles when joining them into one coverage.

CONT

Edge Matching [is an] important part of the creation of a digital map or GIS database. One digital map may encompass many paper maps, but when the paper maps are laid edge-to-edge, features running across boundaries of the map sheets are not always properly aligned. These misalignments occur for many reasons including survey error, cartographic generalization, and problems of map projection and compilation. Edge matching is a term applied to a variety of techniques employed to resolve these inconsistencies, including warping and rubber sheeting.

OBS

edge matching: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

French

Domaine(s)
  • Radar, radioguidage et radiogoniométrie
  • Engins spatiaux
  • Télédétection
DEF

Élimination des erreurs spatiales et de contenu produites aux limites de feuillets cartographiques ou de tuiles lors de leur fusion.

OBS

agencement des contours : terme uniformisé par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).

Spanish

Campo(s) temático(s)
  • Guía radárica, radioguía y radiogoniometría
  • Naves espaciales
  • Teledetección
DEF

Operación que consiste en ajustar las entidades lineales localizadas en los bordes de dos mapas adyacentes con el fin de hacerlas coincidir lógicamente en un mapa digital continuo.

Record 3 2005-04-20

English

Subject field(s)
  • Remote Sensing
DEF

The generalization of cartographic representation of the object before digitising, including displacement, simplification, etc.

CONT

Spatial generalization involves pixel resampling prior to analysis and resampling or grouping after analysis to meet a minimum map unit. As stated previously, resampling to a spatial resolution finer than the original data commonly results in substantial error.... Post-classification data generalization takes on two forms, spatial and thematic.

OBS

spatial generalization: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

Key term(s)
  • spatial generalisation

French

Domaine(s)
  • Télédétection
DEF

Généralisation d'une représentation cartographiée d'un objet avant de procéder à la numérisation.

CONT

L'utilisation d'une image actuelle permettra de tester, d'évaluer la reproductibilité dans le temps et la généralisation spatiale sur une plus grande région du massif pyrénéen de la méthode implémentée ici.

OBS

Traitement post-classification.

OBS

généralisation spatiale : terme uniformisé par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).

PHR

Généralisation spatiale par filtrage de la classification.

Domaine(s)
  • Mathématiques
