About this app

Have you ever been flustered in the field by tangled and overlapping cadastral map lines, disconnecting internet, and complex manual calculations?

'Smart Loss Assessment' is an ultra-precise spatial information and field survey solution designed to allow Crop Disaster Insurance Loss Adjusters to complete everything from complex field surveys to yield calculations with just a single app.

🧮 Field-Customized Assessment Calculator Exclusively for Loss Adjusters

Leave Excel and handwritten calculators in your car! We provide an automatic calculator dedicated to 10 specific crop items that fully applies the formulas found in the operational manuals.

🌶️ Chili Pepper Production Cost Guarantee (Latest '26 Model): Automatic verification of logical date errors by pre- and post-harvest period, and warnings for exclusions when the regional coverage period (130/150 days) is exceeded. Automatic application of recognition rates by pest and disease grade (Grades 1–3) and preparation stage production cost coefficient (55.5%)

🍏 4 types of fruit trees (Sweet Persimmon/Astringent Persimmon/Apple/Pear): Support for precise survey of fruit bruising rate and leaf fall rate (automatic calculation of elapsed days)

🍎 Fruit set (after thinning): Automatic calculation of the number of trees subject to survey and sample allocation in 0.1 seconds upon input of the number of enrolled/dead/uncompensated trees by variety. View results cleanly using the sample hiding feature

🍵 Tea Damage Rate: Enter the number of previously harvested/current teas per 2 buds → Automatic conversion of effective weight index → ​​Calculation of final damage rate

🧄 Garlic Yield: Automatic application of warm-climate/cold-climate variety coefficients and estimated growth ratios, automatic determination of planting density suitability

🧅 Onion Yield: Automatic calculation of estimated growth ratios and damage rate based on remaining days

🥔 Potato Yield: Automatic conversion of damage severity ratios by pest/disease grades 1, 2, and 3, and calculation of damage rate

🎃 Butternut Squash Yield: Damage rate calculated by summing yields from the 3rd survey

🫐 Blueberry: Calculation of damage rate linked across 3 stages: flower bud → flower → fruit (automatic reflection of weights)

🌾 Paddy Crops (Rice/Glutinous Rice/Flourishing Rice/Wheat/Barley/Oats): Supports 3 methods: sample survey, full enumeration survey, and yield factor survey; single pest/disease incidents Automatic application of 70% limit and standard moisture content

▷ Calculator Common Convenience Features

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

· Automatic calculation of estimated average yield

· Automatic generation of commas (,) for monetary units and automatic row addition if sample interval is insufficient

· Automatic capture of the entire summary report and saving to gallery in high resolution

💾 Multi-Survey History Management & Secure Backup (Pro)

Exerts powerful capabilities when conducting repeated surveys of the same crop across multiple farmlands. · Enter Farm Name/Land Name and Save → 100% Recovery and Retrieval at Any Time

· Automatic Filtering by Item (Onion records only in the Onion tab, Chili records only in the Chili tab)

· [NEW] Data Backup & Restore: Select 'Data Only' or 'Include Images' for lighter storage and safe restoration even when changing devices

· [NEW] Automatic backup notifications when a certain amount of measurement records accumulate to prevent loss of valuable data

🗺️ Ultra-Precise Area Measurement & Cadastral Map Fusion

· Add, Exclude, or Individually Delete Zones: Drawing uncompensated zones such as ponds or cemeteries accurately deducts them from the total area, allowing you to pinpoint and delete only the incorrect zones

· Instant Error Rate Check: Real-time comparison of the error rate (%) with the actual area when entering the subscribed area (standard)

· Slope Correction Area: Automatic correction of the actual slope area by measuring the slope angle

· GPS Signal Strength Display: Check the current location error radius (±m) at a glance as Good, Average, or Weak, and display the number of measured points in real-time

🪄 One-Click Cadastral Map Extraction and Analysis of Incorporated Parcel Numbers (Pro)

· Automatic Parcel Number Drawing: Long-press the desired parcel to automatically extract cadastral boundaries in just 1 second via integration with the National Spatial Information System (VWorld).

· Area Analysis by Parcel Number: Automatic analysis of land use classification (building land, dry field, paddy field, etc.) and incorporated area (㎡·pyeong·ratio) for each parcel incorporated within the measurement area. Fine error of less than 1% and automatic filtering of roads and rivers

· Interpretation Guide: Since the screen location in aerial photographs may differ from the actual location, we advise prioritizing walking (GPS) measurements when boundaries are ambiguous.

✈️ Viewing Historical Time-Series Aerial Photos (Pro)

· View high-resolution aerial photos from the National Geographic Information Platform by year (2011–present) to identify the history of farmland development, such as orchards, and topographic changes.

· Automatically searches for the nearest new year when a year without data is selected, and mobile rendering is optimized.

🛰️ Satellites from 3 Agencies & Powerful Offline Mode

· Freely switch between Kakao & Naver cadastral maps + Google satellites + Ministry of Land, Infrastructure and Transport historical aerial photos + offline canvas.

· Real-time rotation of your location marker in the direction you are actually facing via compass integration.

· [Upgraded] Offline Mode: Automatically switches to a blank map without data consumption in cases of internet disconnection, such as in remote mountainous areas. Fully supports two-finger zoom and drag panning.

🚶 Field-specific GPS tracking (Walking/Vehicle Mode)

· Automatically plots points and calculates area along the trajectory of walking or vehicle movement.

· Walking Mode: Automatic GPS error filtering based on walking speed.

· Vehicle Mode (Pro): Fast measurement cycle optimized for high-speed movement, such as tractors and vehicles.

🛠️ 3-Piece Field Survey Tool Set

· Haptic Quantity Counter: Accurately count fruit set and damaged crops using vibration feedback without looking at the screen.

· Sample Number Display: Displays sample numbers in full screen for field photos and captures immediately.

· Field Memo: Record survey details, farmer interview records, specific field observations, and more.

🎯 Highly recommended for:

** · Crop damage insurance adjusters and field investigators who need accurate damage area calculations and meticulous yield survey formulas every day

· Real estate agents and developers who need land inspections, cadastral map verification, and parcel analysis

· Agricultural workers and those returning to farming who want to personally verify the boundaries and area of ​​their land

※ Important Note

The cadastral maps and area calculation information provided in this app are reference data based on the National Spatial Information Open API and device GPS modules. They cannot be used as legally valid drawings or official survey data, and the values ​​calculated by the damage rate calculator may differ slightly from actual computer input values ​​due to revisions in operational manuals or differences in decimal point processing standards.

🚀 스마트 손해평가 v1.1.50 업데이트

[✨ 주요 업데이트]
🍎 적과후착과수에서 품종명을 입력하면 그룹이 자동 선택됩니다(예: '루비에스' → 4그룹). 등록 품종명과 일치할 때만 인식됩니다.
🍎 그룹·재배방식 입력란은 평소 접혀 있다가, 가입주수 대비 실제결과주수가 5% 초과 차이나는 계약변경 대상일 때만 자동으로 펼쳐집니다.
🌽 옥수수 품종 표준중량 표시, 표본표 갯수·피해수확량 표시를 다듬고 세부 계산 로직을 점검했습니다.
🔧 옥수수 손해액·보험금 계산과 착과율 보정의 세부 로직을 점검해 표시값과 계산값이 항상 일치하도록 정리했습니다.

💡 개발자의 한마디
품종명만 입력하면 그룹이 자동으로 잡히고, 계약변경 대상일 때만 추가 입력이 열리도록 손봤습니다. 현장에서 조금이라도 손이 덜 가시도록 계속 다듬겠습니다. 소중한 제보 감사드립니다. 👨‍🌾👩‍🌾
