Best regards. Recently when processing a large number of images, there is a problem orienting the photos of a Phantom 4 survey, which produces spatially warped orthophotos or unfilled voids. ![Imagen](https://global.discourse-cdn.com/pix4d/original/2X/b/bb4e5767d1bbfd28b41f747f66dbf16ad3c8b5f5.jpeg) I would greatly appreciate your help. Sincerely, Diego. ---

Hi @diejodelpi Can you please post the quality report of your project? It’s hard to tell what happened here without having more information. Thank you ---

Saludos cordiales. Recientemente al procesar una gran cantidad de imágenes, se produce un problema al orientar las fotos áreas de un levantamiento con Phantom 4, lo cual al final produce ortofotos deformadas espacialmente o vacíos sin rellenar. ![Imagen](https://global.discourse-cdn.com/pix4d/original/2X/b/bb4e5767d1bbfd28b41f747f66dbf16ad3c8b5f5.jpeg) Agradecería inmensamente su ayuda. Atentamente, Diego. ---

Thanks for sending the report. Could you please give me more information about your license number? Feel free to send me a private message on the community if you prefer to not share the license key here. The first thing that I noticed is that the project is processed using the rapid options: ![3d_maps](https://global.discourse-cdn.com/pix4d/original/2X/d/da44c0b71181292e825970a56cd46dfda40108a2.png) This may reduce the quality of the outputs. I suggest you process your project with the 2D Maps template (not the rapid version). Also, when there are several flights at different flight altitudes, it is recommended to process step 1 for each flight separately, add common manual points and then merge them together. For more information about merging: > **[How to merge projects](https://support.pix4d.com/hc/en-us/articles/202558529-How-to-merge-projects)** > > It is possible to merge projects for which step 1. Initial Processing has already been completed in Pix4Dmapper. This allows the combination of information from different projects into one single... Please keep in mind that your computer may not be able to merge all flights together (especially if you process with the full options and not the rapid ones). I hope it helps. Looking forward to receiving more information about your license. ---

Hi Juan, Try enabling Accurate Geolocation and Orientation. It should fix the problem. ![Accurate Geolocation](https://global.discourse-cdn.com/pix4d/original/2X/5/529f5ff67a1d657fc6494664c83582b80a61e136.jpeg)
