Field identification guides, subsurface investigation planning, and well geometry tools for Alaska geotechnical practice. Includes GIS and spatial tools for survey planning and drone operations. All tools run locally — no internet required after loading.
Field diagnostic reference for identifying pavement distress types and tracing them to geotechnical and structural root causes. Covers 15 FHWA LTPP distress types plus five Alaska cold-climate types: frost heave, thaw settlement, delamination, longitudinal joint cracking, and reflective cracking. Reference photos included.
Interactive USCS-based decision tree for soil classification and rock description. Covers organic soil tiers per Alaska DOT&PF thresholds, dual-symbol fines classification, frozen soil designations per ASTM D4083, and igneous, sedimentary, and metamorphic rock identification. Alaska geological context throughout — Bootlegger Cove, Cook Inlet Quaternary, glaciomarine silts, Péwé loess.
Step-by-step planning tool for selecting drilling methods, rig types, and investigative technologies. Guides decisions from project purpose through site access, depth, ground conditions, and sampling method. Alaska-specific guidance for fly-in access, permafrost freeze-back, cobble and boulder conditions, and remote village mobilization.
Canvas-based cross-section builder for configuring monitoring wells, piezometers, and observation borings. Set borehole diameter, casing depth, screen interval, gravel pack, and bentonite seal, then generate a dimensioned schematic. Supports piezometer, percolation/infiltration test, and monitoring well configurations.
Leaflet-based map tool for planning ground control point layouts ahead of UAS photogrammetric surveys. Draw your survey polygon, enter flight altitude and sensor parameters, and get GSD estimates, GCP spacing recommendations, and a CSV export of planned GCP coordinates.
Interactive reference covering 20 map projections across five families — cylindrical, conic, azimuthal, pseudocylindrical, and miscellaneous. Each entry includes an SVG graticule diagram, EPSG code, distortion characteristics, and Alaska-specific relevance notes. Essential background for GIS, photogrammetry, and coordinate system selection.
FAA Part 107 and LAANC compliance decision tree with a dynamic Go/No-Go checklist. Flags Alaska and Arctic-specific conditions — wind, icing, temperature limits, low visibility, and airspace — that standard pre-flight tools miss. Printable checklist output for field documentation.
