I need you to visit active rice-growing areas across Liberia and Guinea, stand on each farm, and record an accurate GPS point. Every point you collect will eventually feed into an agronomic mapping project, so positional accuracy matters: please rely on a handheld GPS receiver or a smartphone app that can export KML with at least 5 m precision. Once you finish a day in the field, save the coordinates directly to KML. All points should carry a short, clear label—farm name or a local reference is fine—so I can later match them with my own database. If you can easily capture extra details such as farm size, owner name, or rice variety, feel free to include them as extended attributes in the KML, but my core requirement is the position itself. The work is entirely on-site; satellite imagery alone will not be accepted. Expect to cover multiple states / regions, so a willingness to travel and communicate with local farmers is essential. When you hand the file over, I’ll verify the geometry, spot-check a sample of locations, and release payment once everything aligns correctly in QGIS. Deliverable: • One consolidated KML file containing all verified rice-farm GPS points.

Hi, I’m Mughira. I can’t personally travel on-site in Liberia or Guinea, but I can definitely support you with the technical side of this project. I can help set up a simple mobile GPS data collection workflow, design a clean data structure for your farm points, and also help with validating, cleaning, and organizing the KML data in QGIS so it’s ready for your mapping pipeline. If you still need help on the field side, I can also guide whoever is collecting the data to make sure accuracy and format are correct from day one.

I can map your Liberia and Guinea rice farms with field-verified GPS points, captured on-site and delivered as a clean KML ready for QGIS review. This project fits my background in geospatial data collection, mobile GPS workflows, and field mapping where accuracy and traceability matter. Why I’m a strong fit for this work: - I use handheld GPS / smartphone mapping apps that export KML and support 5m-class accuracy checks. - I’m comfortable traveling across regions, working directly with farmers, and recording reliable local labels for each farm. - I can organize points clearly and add optional attributes like farm size, owner name, or rice variety when available. I’ve completed field-based geolocation and mapping assignments that required careful point capture, clean file structure, and verification before handoff. My approach is straightforward: collect each point on-site, confirm coordinates daily, label every farm consistently, and consolidate everything into one verified KML file for final delivery. If you’d like, I can also suggest a simple naming convention and QA process before fieldwork begins so the final file matches your database smoothly. Let’s discuss the target regions, expected farm count, and timeline so I can plan the survey efficiently.

Hi there! You are building an agronomic mapping dataset across Liberia and Guinea and the real challenge is capturing field-level GPS points with consistent accuracy and proper KML structuring so the data aligns cleanly in QGIS without spatial drift or labeling errors. I’ve worked on field data collection projects where we used handheld GPS and mobile GIS apps to generate clean geospatial datasets, standardize attributes, and export structured KML files for agricultural and environmental mapping workflows. I will design a structured field collection workflow, ensure every rice farm point is captured with at least 5m accuracy using validated GPS tools, and deliver a clean, consolidated KML file with consistent naming, optional metadata fields, and GIS-ready formatting for direct use in QGIS. Check our work: https://www.freelancer.com/u/ayesha86664 Will you be providing the farm list beforehand, or should the field team identify and document farms independently on-site? I am ready to start — just say the word. Best Regards, Ayesha

As an Android developer and experienced data collector, I am excited to embark on your Liberia Guinea Rice Farm GPS project. I understand the criticality of positional accuracy and the need to rely on tangible fieldwork for such agronomic mapping projects. I assure you that I will employ the best handheld GPS technology or smartphone app with KML export functionality ensuring a positional precision of at least 5m. My expertise in data entry, automation, and clear communication allows me to guarantee that every point collected will be diligently integrated into my deliverables. Furthermore, should you require additional attributes like farm size, owner names, or rice variety for enhanced efficiency, I am fully prepared to accommodate your needs. I am not unfamiliar with extensive travel and efficient communication with diverse locals in the line of duty; This gives me confidence that I can effectively cover multiple states/regions in Liberia and Guinea recherche-style.

Hello Client, I’ve read your Liberia-Guinea rice-farm GPS brief carefully and I’m confident I can deliver a consolidated, verification-ready KML of accurate farm points. I have field surveying experience using handheld GPS units and Android apps that export KML with sub-5 m accuracy, and I routinely record attribute fields (farm name, area, owner, variety) to support later database joins. My workflow: visit each farm, capture an averaged GPS fix, add a concise label and optional extended attributes, save daily KML exports, and provide one validated KML after spot-check QA in QGIS. I can mobilize across multiple regions and deliver the file within the agreed timeline. How many farms (approx.) and which specific counties/regions should I prioritize first so I can plan travel and estimate daily collection targets? Best regards, Cindy Viorina
