🧮 Dedicated Calculator by Item

100% Application of Formulas from Work Manuals

【Fruit Trees】

🍎 Fruit Set (After Thinning)

Simply enter the number of enrolled, dead, or uncompensated trees by variety, and the number of trees subject to investigation and the sample allocation will appear instantly. Groups are automatically recognized when entering the variety name; sample input fields are grouped separately at the bottom of the screen to display both the variety name and age. Hide samples for a clean view of the results.

🍎 [Pre-thinning Comprehensive / Comprehensive] Fruit Drop/Fruit Set Reduction (4 Fruit Tree Types)

Simply select the risk category to convert the entire formula.

· Pre-thinning Comprehensive: Based on fruit set after thinning. Displays the value before calculation divided by the pre-thinning value, including 7% fruit set loss caused by typhoons for apples and pears.

· Comprehensive: Based on fruit set. When entering the enrollment weight, the yield reduction (kg) is calculated.

· Supports full/sample fruit drop surveys; samples are automatically converted to the number of trees surveyed.

· Reflects the revised damage recognition coefficient (new 30% type: 30%, 50%, 80%, 100%), with maxA deduction.

· For autumn frost damage ('50% or more leaf dieback'), entering only the date of the incident and the expected harvest date automatically calculates the remaining days and the normal fruit coefficient (0.0031 × remaining days).

🍑 [General] Fruit Drop & Fruit Set (Grape, Peach, Plum, Citrus)

Add multiple varieties to simultaneously input and sum the fruit drop and fruit set for each variety. If you enter the fruit weight for a specific variety, the yield reduction (kg) for that variety is displayed; even if you enter only partial data, it indicates which varieties have been included in the sum. Pests and diseases such as peach bacterial spot (coefficient 0.5) are calculated separately according to regulations.

☀️ [Pre-Thinning Comprehensive] Sunscald Damage

Entering fruit set and fruit drop (total count/sample) automatically calculates the number of sunscald-damaged fruits, the number of recognized reduced fruits, and the damage rate. Reflects compensation standards (6% for apples, pears, and sweet persimmons; 4% for astringent persimmons).

🍏 [Pre-Thinning Comprehensive] Young Fruit Bleeding Rate and Leaf Drop Rate — Automatic calculation of elapsed days

🫐 Blueberry — Damage rate linked in 3 stages: flower bud → flower → fruit (automatic weighting)

【Field Crops · Paddy Crops】

🌶️ Chili Pepper Production Cost Guarantee

Automatic verification of logical date errors by pre- and post-harvest periods, warning of exemption from liability for exceeding regional guarantee periods (130/150 days), and automatic application of recognized pest and disease grade 1-3 rates and preparation stage production cost coefficient (55.5%). Classification of standard growth days (100/70 days) for red/green peppers, automatic calculation of copayments, and even generation of survey images.

🌾 Paddy Crops (Rice, Glutinous Rice, Flourishing Rice, Wheat, Barley, Oats)

Supports three survey methods: Sample Survey, Complete Survey, and Yield Factor Survey. Automatic application of a 70% limit for single-incident pest or disease damage and standard moisture content.

🌽 Corn — Calculates damaged yield, loss amount, and estimated insurance payout upon input of upper, middle, or lower sample sections and furrow specifications. Automatic subscription price by region (Gangwon 2,044 / Nationwide 1,793 KRW)

🎃 Sweet Pumpkin — Summing method of 3rd survey yields

🥔 Potato — Automatic conversion of damage ratios for Pests and Diseases Grades 1, 2, and 3

🧄 Garlic — Determination of variety coefficients for warm/cold types, estimated growth ratio, and planting density suitability

🧅 Onion — Automatic estimated growth ratio based on remaining days

🍵 Tea — Number of previously harvested/current teas → Automatic conversion of effective weight index

▷ Calculator Common Convenience Features

· Automatic contract change warning if actual area error exceeds 10% compared to subscription area

· Automatic calculation of estimated average yield

· Automatic generation of commas for amounts, automatic addition of rows if sample interval is insufficient

· Capture the entire summary report and save it to gallery in high resolution

🗺️ Ultra-precision area measurement & Cadastral Map

━━━━━━━━━━━━━━━━

· Multi-zone measurement and summation. Ponds, cemeteries, and buildings are accurately deducted from the total area when drawn as 'exclude zones'.

· Individual zone editing: Select and delete or rewrite only incorrectly drawn zones.

· Real-time comparison of error rate (%) with actual measurements when the registered area is entered.

· Slope correction converts projected planar area to actual slope area (useful for mountain orchards).

· Length measurement mode, displays elevation of the first point.

· Fine movement of the last pin in 10cm increments using the joystick or directional buttons.

🪄 One-Click Cadastral Map (Pro)

Long-press a parcel to extract boundaries in just 1 second via integration with the National Spatial Information System (VWorld) and convert it into a measurement zone. It automatically analyzes land classification (building land, dry field, paddy field) and area (㎡, pyeong, ratio) for each incorporated parcel, and automatically filters out fine errors of less than 1%, as well as roads and rivers.

✈️ Historical Aerial Photos (Pro)

View high-resolution aerial photos from the National Geographic Information Platform by year from 2011 to the present. Use this for comparing pre- and post-disaster conditions and determining the optimal timing for orchard establishment.

🛰️ Multi-Map Engine & Offline

Freely switch between Kakao/Naver cadastral maps, Google satellite imagery, Ministry of Land, Infrastructure and Transport aerial photos, and an offline canvas. The compass is integrated to rotate the map in the direction your location marker is facing. In remote mountainous areas without internet access, it automatically switches to a blank canvas to continue measurements without consuming data (supports two-finger zoom and drag).

🚶 GPS Tracking

Points are automatically plotted along your walking or vehicle trajectory, and area is calculated in real-time. Walking mode filters out erratic signals based on walking speed, while Vehicle mode (Pro) quickly measures large parcels. Signal strength and margin of error (±m) are always displayed.
