Titles By Jim Crume
Coordinate Transformations that include Northing/Easting datum shift, Elevation adjustment, Scaling, Rotational, Grid to Ground, Ground to Grid and Grid Bearings to Geodetic Bearings.
Surveying formulas from the eBook series, Book 1 through 10, and other useful formulas that are used on a daily basis compiled into a handy eBook for easy reference.
Professional survey mapping is much more than just knowing how to fly a drone. This series of books will provide a step-by-step process to completing and mastering the use of a drone for 3D Survey Mapping. Global Mapper helps to bridge the gap between Metashape Pro and Civil 3D. GM has many useful tools. Only those tools that are helpful for 3D Survey Mapping are shown in this book. You are encouraged to research all of the other features that GM has to offer. GM is an amazing software solution for today’s modern mapping techniques.
Surveying Mathematics Made Simple - How to add, subtract and convert between Bearings and Azimuths
A complete workflow for Drone Mapping from client request, estimating a project, mission planning, flying the mission, processing the data, preparing the deliverables to completing the project.
Create rectangular coordinates given a bearing and distance.
This book is a step by step on how to build a spreadsheet with formulas for calculating flight parameters for 3D mapping drones. This book expands on the details shown in the Litchi book. There are many drones that are available that are capable of performing 3D mapping. They will vary in sensor sizes and AGL altitudes needed to capture the accuracies that are required to obtain the necessary resolutions for survey design level mapping. Many flight applications will automate the process but will limit what you have control over such as the speed of the drone, capture rate, etc.
This book will walk you through the process to manually fly a project site using the Mavic Mini for an orthomosaic. The Ground Control Points are extracted from Google Earth.This is a low costs solution to capture high quality rectified orthophotography on a reduced budget. This a great affordable way to get into GIS mapping for everyone.
This book is a step by step guide on what type of stakes are needed and how to set them such as Slope Stakes, Ditches, Minor Structures, Major Structures, Water, Sewer, Dry Utilities, etc. Includes a special section on Grid vs Ground coordinates.
Mastering the RPN & ALG Calculators: Step by Step Guide (Surveying Mathematics Made Simple Book 18) Nov 6, 2015
One of the Keys to passing a Surveying and Engineering mathematics exam is Mastering the Calculator. This book outlines the basic functions of a RPN and ALG calculator that are needed to solve most equations that will be found on an exam.
Inverse between two coordinate pairs to determine bearing and distance.
