Survey Toolbox vs Digital ROW Utilities

Survey Toolbox คือเครื่องมือคำนวณสำหรับงานสำรวจและวิศวกรรมโยธา ออกแบบมาเพื่อให้ช่างสำรวจ นักศึกษา และวิศวกรภาคสนามสามารถคำนวณค่าพื้นฐานได้อย่างรวดเร็วและแม่นยำ แอปนี้รวบรวมสูตรสำคัญ เช่น • การคำนวณ Azimuth และระยะทาง (ΔN, ΔE, Distance, Azimuth) • การตรวจสอบค่าคลาดเคลื่อน (Deviation, CH, O/S) • รองรับทั้งหน่วยองศา DMS และหน่วยทศนิยม • บันทึกผลลัพธ์และแชร์ได้ทันทีผ่าน LINE หรืออีเมล เหมาะสำหรับช่างสำรวจภาคสนาม นักศึกษาวิศวกรรมโยธา และผู้ที่ต้องการความแม่นยำในงานวัดระยะทุกประเภท ต้องสมัครสมาชิก Pro เพื่อปลดล็อกเครื่องมือทั้งหมด Survey Toolbox is a professional field surveying calculator for civil engineers and surveyors. It provides fast and precise computations for essential surveying formulas such as: • Azimuth and Distance (ΔN, ΔE, Distance, Azimuth) • Deviation checks (Deviation, CH, O/S) • Supports both DMS and decimal degree input • Save and share results instantly via LINE or email Perfect for field surveyors, civil engineering students, and professionals who value accuracy and efficiency in their surveying tasks. Full access requires a Survey Toolbox Pro subscription. Unlock all professional tools, including curve calculations, result recording, and offline use, by subscribing to Pro.

Digital ROW Utilities helps contractors, utility engineers, and inspectors document underground and aboveground utility infrastructure in the field. CAPTURE AND DOCUMENT • Capture point and linear features with location measurements and recorded uncertainty. • Attach field photographs, asset attributes, material certificates, and inspection notes. • Measure visible surfaces and trench geometry with LiDAR on supported devices. • Review on-device infrastructure detection candidates before adding them to your project. MAPS AND REFERENCE DATA • Browse public WFS and ArcGIS reference sources. • Import KML overlays, PDF plan sheets, and georeferenced imagery. • View captured assets and reference overlays in augmented reality. • Review extracted plan-sheet symbols, lines, and tabulations before accepting them. REVIEW AND DELIVER • Record ASCE 75-22-oriented utility attributes and positional accuracy information. • Review data completeness, provenance, and quality-level justification. • Capture collector, reviewer, and professional signature records for your review workflow. • Export GIS and civil-design formats, PDF reports, and deliverable packages with file hashes. • Publish to your own configured ArcGIS destination using your credentials. LOCAL FIELD WORKFLOW • Organize projects, permits, photos, and scans on your device. • Undo edits and recover a previous session snapshot when possible. • Exchange session bundles with another device through a user-selected sharing method. • Prepare permit packets and follow the selected agency's filing instructions. Phone positioning retains the device's measured accuracy. A correction-stream connection alone does not improve phone accuracy or establish an RTK fix. LiDAR and AR availability depend on device hardware. Utility investigation quality and professional compliance require appropriate evidence and review; the app does not certify them automatically from GPS precision. Cloud account synchronization and external accessory GNSS connectivity are not enabled in this release. Permit packet preparation does not constitute agency acceptance or an 811 ticket.
