I am looking for an experienced freelancer to help me interpret a false-color vegetation map of a natural area.

3D Building Footprints Digitization . Specification: 1. All building footprint need to be digitized including apartments, skyscrapers, commercial, residential, garage, shafts etc... 2. Floor wise splitting need to be done 3. Open area need to be removed from BFP. 4. Given images is top projected Ortho image so unwanted base movement is not required. 5. High planimetric accuracy is required (+/-0.5 meters) 6. In case Building is hidden due to adjacent building height then user need to update by taking reference from Google image 7. Building orientation must be according to provided images (90 degree angle). Maintain orthogonality in database 8. Juts & notches need to be create properly. 9. Shoe box is needed to be digitized. 10. Parapet Wall is digitized with buffer of (-...

Objective: To create a 3D model of the subsurface magnetic properties using magnetic inversion techniques based on the data obtained from the recent magnetic survey. Tasks: Data Preprocessing: Review and organize the raw magnetic survey data to ensure quality. Remove any environmental noise or anomalies from the data. Convert the raw data into a usable format for magnetic inversion. Magnetic Inversion: Choose an appropriate magnetic inversion algorithm based on the survey area and subsurface geology. Set the inversion parameters to optimize the accuracy and resolution of the 3D model. Run the magnetic inversion algorithm on the preprocessed data to generate a 3D model of the subsurface magnetic properties. Interpretation and Analysis: Analyze the magnetic inversion re...

Attached in DWG format, a subdivision plan spread over neighborhoods called subdivision sectors. These subdivision sectors are divided into blocks. Each block bears address numbers. In these districts, a distribution network has been set up to which the blocks will be connected. The purpose of our work is to map and set up an access database integrated into the arcgis system, to be able to respond to the following queries: - Identify the closest network to house n°X - Know the direction of flow to this house. - Be able to locate the closest valve to the network that supplies this house. If this valve is closed, which houses will be affected. - Be able to estimate the flow pressure of each house. - Be able to represent all the pipes that make up the network. - Be able to repr...

HI! I created a whole universe, Shiner State, a fictive American state where my roleplaying games occur. I have multiple maps, and I need some modifications, from simple ones to more complex ones. I attached my maps to show you. For example, in Shiner State, I want to rethink the road system, create a national park and upgrade its look (not including everything, but to give you an idea of the work). The source file is a .ai, and speaking French is a plus. I won't consider automatic submissions, and your ability to speak french needs to be mentioned in the application. In Mallentown, I want to extend it by a kilometre north and west and add some areas. Shiner City needs more specifics modifications. Thank you!
