Créer une carte numérique sur ArcGIS est un processus simple et facile. Vous pouvez créer une carte en utilisant l’interface utilisateur de Map Viewer. Voici les étapes à suivre:
Connectez-vous à votre compte ArcGIS.
Cliquez sur l’onglet “Cartes” pour accéder à Map Viewer.
Choisissez un fond de carte pour votre carte.
Ajoutez des couches à votre carte en cliquant sur le bouton “Ajouter”.
Personnalisez votre carte en modifiant les styles de couche, les étiquettes et les symboles.
Configurez les fenêtres contextuelles pour afficher des informations supplémentaires sur les entités de la carte.
Enregistrez votre carte et partagez-la avec d’autres utilisateurs.
Si vous avez besoin d’aide pour créer une carte numérique sur ArcGIS, n’hésitez pas à me le faire savoir. Je serais ravi de vous aider davantage.
Data Acquisition:
Get a high resolution topographic image for the "Wilaya of Biskra". Make sure the image is in a format supported by ArcGIS.
Start ArcGIS:
Open ArcGIS on your computer.
Create a New Map Document:
Open a new map document in ArcGIS.
Add the Topographic Image:
Use the "Add Data" tool to import the topographic image into your ArcGIS project.
Scanning:
Activate the "Editor" toolbar and select the "Create new entity" option. Digitize features in the image, such as administrative boundaries, waterways, and roads, using the available drawing tools.
Calibration:
Use the "Georeferencing" toolbar to add control points at well-distributed locations on the image. Assign known WGS84 coordinates to these points to calibrate the image.
Georeferencing:
Use the georeferencing tool to adjust the digitized features to the actual coordinates of the "Wilaya of Biskra". Add as many control points as necessary to ensure optimal accuracy.
Registration of the Georeferenced Map:
Save the georeferenced map document to retain spatial information.
Vectorization - Polygons, Points, Lines:
Use the tools on the "Editor" toolbar to create vector data layers. For example, create separate layers for polygons (administrative boundaries), points (landmarks), and lines (roads). Scan these items using the appropriate tools.
Data Attribution:
Add attributes to newly created vector features. For example, assign names, codes, or other relevant information to each item.
Verification :
Check the spatial and attribute coherence of your map. Make sure the elements are positioned correctly and the attribute data is correct.
Final Recording:
Save your final map document.
Export:
Export your map to a final format, such as PDF or JPEG, if necessary.
