Hello and welcome!
I am an architectural designer with 3 years of experience creating architectural sketches, concept drawings, and visual presentations for residential and commercial projects.
I specialize in transforming ideas into clear and attractive architectural sketches that help clients visualize their projects before development. Whether you need a conceptual building sketch, facade drawing, site concept, or presentation sketch, I am here to help.
FAQ
What software do you use for processing?
I use industry-standard platforms including Pix4Dmapper, Agisoft Metashape, Esri Drone2Map, and Global Mapper. I select the best workflow based on your project requirements and desired output format.
Do I need to provide ground control points (GCPs)?
GCPs are strongly recommended for survey-grade accuracy (sub-5cm). Without GCPs, I can process using onboard GPS with accuracy typically within 1-3 meters. I can guide you on GCP placement if needed.
What drone data formats do you accept?
I accept JPEG, TIFF, RAW images with embedded GPS metadata. I also process DJI Phantom, Mavic, Matrice, and Autel datasets. For LiDAR, I accept .las, .laz, and .e57 formats.
Can you deliver CAD-compatible files?
Yes. I export to DXF, DWG, Shapefile, GeoTIFF, KML, and point cloud formats (LAS, PLY, XYZ) compatible with AutoCAD, Civil 3D, ArcGIS, QGIS, and Revit.
How accurate are the final deliverables?
With proper GCPs, accuracy is typically 1-3 cm horizontally and vertically. Without GCPs, accuracy depends on drone GPS quality, usually 1-3 meters. I'll specify expected accuracy in my delivery notes.
